QGLWidget is just a widget, not a ui framework. We had managed to work
Harmattan nicely back then with it, but was it a nice software underneath?

More importantly, widgets have certain limitations, but I do not think that
can only be solved by QML. I treat QML just as a means for a goal, whereas
C++ could be another.
