As a beginner I like the look and the code style of GTK+3 and the tutorial. The problem is that I can't understand how to install it. https://wiki.gnome.org/action/show/Projects/PyGObject?action=show&redirect=PyGObject https://python-gtk-3-tutorial.readthedocs.org/en/latest/index.html
Until now I have failed. For the meantime I started playing with PyQT and wxpython and see what is best. At least they are much easier to intall even PyQt is hard to code for me and wxpython is less attractive when it comes to looks.
