It looks like the people at Qt are thinking of this as well.
http://qt.nokia.com/developer/qt-roadmap/ mentions Maps/Navigation API and while the details are really scarce (it's only a roadmap, so that is expected), it does state that:
"Provides an API to access maps, landmarks and route information for navigation."

Now just to find some troll from Qt who could open that up a bit.
