GUI in Python for Raspberry, what to implement?

Question

Python

Hello. I set out to write an on-board computer on a raspberry for my motorcycle until next spring.
After torsion in my head - one very important question arose - on which library to implement a graphical interface? Naturally, everything is written in Python. The interface is still quite complicated, so primitives will not work here. The first thing that catches your eye is Kivy. But it’s not clear how to work with it humanly, since there is no designer like in the same PyQT (I haven’t dealt with layout by hand yet).
On the raspberry itself, it is supposed to connect a 5-7 inch screen via HDMI to display information on the tidy.
It is desirable that there would also be the possibility of scaling the interface to different screen sizes out of the box.
Thank you.

Alternatively, render as a web page.

Why isn't PyQt suitable? You can try PyGObject (like GTK+ for python) if you want something more lightweight than Qt.
