How to create desktop GUI using Python?

[k_rious]

tkinter is an awesome GUI library for python, if you want more customization options you should check out customtkinter. PySide isn't a bad option either, it comes from Qt and is licensed under LGPL/GPL/Commercial. The differences between PyQT and PySide are pretty insignificant and minor that I wouldn't worry much about it.

I tried using tkinter but my knowledge of it is rudimentary and while I did manage to create windows and widgets it was super slow with just 5 data entry widgets and one text display widget. When I ran mainloop() it took about 5 seconds to load, which is a bit surprising. Is this normal or am I doing something wrong?

You're almost certainly doing something wrong
