I realize this is a very broad question, so to help I’ll mention that my primary experience with any programming language is Python. I’ve looked into C and C++ as well, but I haven’t written much in them; in part because they’re more involved, and in part because I get lost in the IDE weeds with’em (whether choosing an IDE or getting it configured to even get started tbh, but that’s mostly a different topic).
In Python I know there’s an option in Tkinter, and I’ve worked with it to some extent but never got entirely comfortable with it. Maybe it would be best to try making some more stuff with it instead of bouncing around different things, but would that be advisable over something that may be better suited to the task?
If it would be better to stick with it, what might be some things you wish you’d known starting out with GUI programming (whether particular to Python or generally applicable)?
I’d argue pyside is preferred to pyqt (pyside2 is the latest bindings for qt5 iirc). And personally, Ive found its documented very well and there are a lot of great (and not great) examples to find on the web.
I started learning c++ through qt, so imo pyside is a great way for UI logic in an easy language -> take known UI logic to c++ -> learn c++ more in general -> learning a second language opens you up to any subsequent languages because of how it teaches you to think. (Not that c++ is useful as a second language specifically, just another language in general starts opening you mind up a bit, especially if it uses different paradigms)
Edit: oh god, pyside6 is the latest. https://www.pythonguis.com/blog/pyside-tutorial-now-available/
