What is your point here? Originally it was announced even before Maemo5 launch that Maemo6 (now MeeGo) will be moving to QT, everybody has known that. Now with MeeGo there will be GTK support too. Sygic doesn't look like GTK application and my guess is that they are using their own graphics toolkit (maybe OpenGL based?), because the applicaiton looks the same as in iPhone for example.
