If my understanding is correct your is not a 3D viewer, isn't it? In one of my projects [1] i used the Qt Graphics View Framework from python. It is not a specific control for maps but worked well for me. If you need a more advanced component you could give a try to the Marble Widget [3]. Personally I have still never used it in one of my projects but it seems to be very powerful.
