Maybe there is some misunderstanding. By the "native widgets" I mean 
Windows Common Controls - buttons, combo boxes, status bars, etc.

This is the note from a Qt developer I was referring to 
http://labs.trolltech.com/blogs/2007/08/30/say-goodbye-to-flicker-aliens-are-here-to-stay/

And right now I can see (using spy++) I that Qt (4.4.3) applications are 
using only one native window handle per top level window. There are few 
more hidden window probably used for worker threads and reserved for 
stuff like tooltips etc...

That makes me think Qt might be using GDI (DrawEdge, DrawFocusRect, 
etc.) or Themes API to draw widgets that looks native. But surely they 
use their own "widget logic".
