Python: GUI programming on raspberry pi/arduino

[erotavlas]

Hi,
I'm looking for a software/library that allows to create a simple GUI (buttons, check box, menù, etc.) that is able to implement several functions (switching on a light, powering a motor, etc.) via GPIO of a raspberry pi (or output of a microcontroller as arduino).
I know these projects: processing (java), wiring (C++), fritzing (maybe the last is the most complete).
Moreover, for python I found this project https://micropython.org/ and this project https://openmv.io/ tailored to solve computer vision problems with microcontroller.
Do you know about similar projects? What is the best in your opinion?
At the moment I'm planning to use python + Tkinter for GUI and udoo for raspberry pi + arduino.
Do you think that pyQT could be better than Tkinter? Is there any visual python software? I'm interested about something cross platform.
My future goal, is to use it in a secondary school.

Thank you

I found the best solution, I think. I'm going to use Qt designer together with python libraries through pyqt5 library and with raspberry pi.
Best Regards
