While this issue has been closed, may I know if there is a wheel for python 3.7 with gtk2 binding?

I'm currently using https://extras.wxpython.org/wxPython4/extras/linux/gtk2/fedora-26/wxPython-4.0.3-cp36-cp36m-linux_x86_64.whl

Thank you!

If I remember correctly, the reason I disabled gtk2 builds for Fedora-28 is that one or more of the dependencies did not have dev packages in the stock Fedora repositories. Without those wxWidgets/wxPython can not be built for gtk2

Thank you for reply.

Does this mean there won't be gtk2 bindings for Fedora any more in the future? Do you still remember those package names? Can we get them from rpmfusion or other sources?

I don't remember, but I expect they are available elsewhere. For the wheels I build I prefer that they do not require things that are not available from the distro's default repositories. I don't always follow that rule but so far it's only been broken for fetching versions of Python from other sources, not for UI library build dependencies.
