I've only enjoyed two GUI frameworks: MSVS and Godot. Trying to build a GUI in code is just rough and while web has the potential to be nice, the over complicated rules make it a slog. Much better to use a WYSWYG editor and glue that to your actual application code.
"What about my sweet Linux GUI framework!" You might interject. But here's the thing: if I'm targeting Linux I'm just gonna make a CLI app anyway.
I haven't actually thought about making a GUI app within Godot. I have played with it before and it is amazing to work with for games. I think I might actually try Godot out and see if I can make a quick GUI application out of it.
