I am currently coding an app for Raspberry Pi, the app is very GUI dependent.
During my research i saw online that tktinker is good for small/simple apps.
I got really excited for PyQt but found out that there is a licence involved which is like $550.
found also PySide which is super similar to PyQt but I've read that it is no longer being maintained by the community, and that the garbage collection well is garbage.
I am looking for something similar like PyQt (designer tool) and free or not as expensive as PyQt.
My Dev environment is windows since am not in the US the PI that I purchased is taking like 3 weeks to arrive so all my testing is on Windows, but the targeted device is RPI 3.
