This was exactly what I was about to answer. Going to QGW is the wrong 
approach for this problem. Unless of course there are other reasons for 
doing it. But it sounds like the OP is only converting to QGW to do this 
one thing.

You can create any QWidget with the top widget as parent and call 
raise() to bring it to the front of the other widgets. That will give 
you an overlay widget inside the window.

For overlays, I usually do this:

     setAttribute(Qt::WA_TranslucentBackground);
     setFocusPolicy(Qt::NoFocus);

in the constructor.
