Yes, it is :) But for something like GQRX, you wouldn't even need to
write your own QT sink -- just use the existing waterfall.

Basically, assuming you actually want to build a GUI application, you'd
approach it like this:
1. Using QtCreator to build the form like you just did
2. Use pyuic4 -s formfile.ui to create a standalone runnable Qt Python
application
3. Merge what python GRC generates for a signal processing flow graph
with that python, adding the PyQt Widget representations to the "blank"
spaces you left for e.g. your waterfall.

You can also just take the route of using the normal GNU Radio GUI hints
etc.; I don't have examples right at hand, but
/usr/share/gnuradio/examples/digital/demod/mpsk_demod.grc has a tab widget.

Best regards,
