Mount Media is a simple program written in bash that can mount devices from a GUI. It does require zenity though, because I'm too lazy to learn GTK+ dialogs for C++.
To install, run:
sudo sh install.sh
Make sure you're in the directory that you downloaded Mount Media to.
After it installs, it should show up in your start menu under either "Accessories" or "Settings".
For Arch Linux, run:
sudo pacman -Syu zenity
For Ubuntu and Debian and pretty much any other distro that uses apt:
sudo apt install zenity
Keep in mind that this is a graphical program. If you're running an OS headlessly, this program won't work for you.
