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.
