Well, if your source code tree starts in gnuradio, you'll find the 
qt-gui stuff in gnuradio/gr-qtgui.

c++ code in lib
xml definition for grc in grc

etc.

If you only want to add gui elements to an existing sink, it might be 
possible to modify the existing code, recompile and install.

But you can build your own module, too.But you have to consider some qt 
programming rules.
 You can  find an example of an 'qt-gui picture sink' to display noaa 
pictures on
