for the python environment I use poetry which I think works well (https://python-poetry.org/ https://python-poetry.org/). As for the licensing (and someone correct me if this is wrong), you have the option to go with PyQt which is GPL licensed and will require you to open source your code, if you go with PySide which is LGPL licensed you do not (unless you make modifications to the Qt code itself which I suppose you're not). So the latter is the better option if you just want to distribute an app. You don't need to use Qml at all and can use QtWidgets instead which is just their traditional toolkit, or you can combine both. I tried Qml for parts of the UI and it's fairly straight forward. I think QtCreator supports python now so if you want a complete IDE with graphical tools that works well, I just used my normal editor.
