GenerationQ (for "image generation queue") is a cross-platform desktop application (screens below) designed to provide a general purpose GUI for generating images via text2img and img2img models. Its primary target is Stable Diffusion but since there is such a variety of forked programs with their own particularities, the UI for configuring image generation tasks is designed to be generic enough to accommodate just about any script (even non-SD models).
Where it differs from a CLI (beyond just being visual) is that it manages a queue for you of generation tasks to be run, and gives a nice UI for prepping input images for img2img—and comes with an in-app "gallery" and a place to review completed tasks.
NOTE: This is not functional for actual image generation yet! I did the parts that require specialized knowledge around UI/UX/JS-frontend-stuff/Electron, and figure others who aren't particularly into that stuff but want a nice UI might pick up from here. This README includes additional sections to facilitate that process.
NOTE2: Security. The current design is centered around taking a "command" and arguments in a very general way, and executing them through Node's child_process.exec or similar. I can see how in certain contexts this would be... extremely sketchy, but I believe doing it in this context should be fine as long as Electron's security guidelines for interprocess communication are followed. If not—if there's some fundamental issue here—feel free to let me know and I'll update this. If that is the case, it will mean the generality of this design is non-viable: BUT, it could still be specialized for more particular uses, i.e. tied more strongly to a particular model/script/params.
Please do whatever you'd like with the source, I just put this together to continue the spirit of good will from the Stable Diffusion release (plus the design reflects what I want to use for image generation myself, so imo it should exist). If people want to add PRs here rather than forking... I'd participate as time allows, but I've never really done anything with open source + have a bit too much going on already. Feel free to message me with questions though.

Note: The project is currently configured to use Electron-Forge, which I personally have not had good luck with (came with boilerplate I used to bootstrap project). And, the one time I tried making a production build for GenerationQ, the executable seemed overly large and the startup time was ludicrous (running dev server was quicker). I would recommend switching it over to Electron Builder.
If you've never used Electron before, the first thing you need to know is that it manages two separate processes: one of them is a Node process and the other is a Chromium javascript process, and the two have to pass messages to each other (Electron docs cover this, but they're a bit involves; can probably just follow the pattern already in place).
The two processes are called Node and Renderer.
The next bit is going to cover the top-level interactions between the program's core structures:
GenerationTask.tsqueueProcessor.tsstore.ts(Zustand)preload.jsapp.ts
The Renderer process creates GenerationTask objects which include all the information configured by a user to specify their image generation task—including a shell command to execute and arguments passed to it—and it sends these GenerationTasks to the Node process by invoking window.electronAPI.sendNextGenerationTask(task).
More specifically, that call is made by queueProcessor.js which has an always running loop that checks whether the main task queue (located in store.ts) includes any GenerationTasks whose status is READY (the GenerationTasks are created/configured via GenerationTaskEditor.tsx).
Where does window.electronAPI.sendNextGenerationTask(task) come from? It is defined within preload.js; this is where all the functions mediating communication between the Node and Renderer processes must be defined. Presently includes only one other function handleGenerationTaskProgress which is invoked in app.ts (which executes on the Node side), sending accummulated terminal output to the Renderer process so it can display it to the user (and potentially some other kind of e.g. % complete info later).
Aside from that, the UI is composed of a handful of React components, and the app's core state is held within a Zustand store (store.js).
The very first and most interesting thing to do would be getting it actually working. And the first step in doing that would be to provide a real implementation of handleNextGenerationTask(e, genTask) in app.ts. Currently it just triggers a process to start sending fake terminal output to the Renderer for demo purposes; a real implementation would most likely use Node's child_process.exec(...) to execute the command and args stored in GenerationTasks passed to handleNextGenerationTask.
After this, if the intent is to remain generation model/script-agnostic, a potential difficulty arises: how do you determine where the generated file is located once it's generated? The best I could think to do was have GenerationTasks store an .outputDir which the node process would scan after a command completes in attempt to locate the new file. (Typically the terminal output will include the generated file name which will make things easier; but if this somewhat-iffy procedure ends up failing in some edge case, the UI at least is able to present that fact to users...)
With those two steps completed the program should be fully functional for a wide range of image generation setups. (There are also a number of logical next steps on the UI side, and it may be worth taking a look at todo.txt for some suggestions. Currently they are just notes to myself and possibly illegible, but if someone were to e.g. create an issue for me to expand and create issues for items in there I'd probably do it :)
