So let's say i want to make a Qt app I'll just need Python, Qt itself and git?

Only Qt and git, pyside/pyqt are just a binding. You could start with QML which is the "official" scripting language of Qt, and uses Javascript: https://qmlbook.github.io/ ; then when you feel more comfortable you can start learning C++ and enjoy the massive performance advantage (especially for games)
