Yeah but the list specifically mentions C++, which I think is part of the reason why this category is hard. Python on the other hand is definitely more entry level friendly but it's still Qt. This should be emphasised.
I think PyQt and PySide are in third category: easy but terrible performance.
PyQt and PySide take full advantage of the C++ Qt library. Performance is as good as a C++ native Qt app, as long as you have no logical bottlenecks in Python.
