It probably is, at least until H3r3tic's Hybrid gui lib gets released.

I felt the same way when I started writing luigi.  And unfortunately for 
you, I still feel the same way today. :-)  Meaning Luigi isn't actively 
maintained because I just needed some way to get some buttons and 
sliders on the screen, and now it does that.  I would have used someone 
else's lib if there had been one to use.  It only has 1-line text fields 
right now, though.  No multiline.  But I did write it with the idea of 
making it extensible in mind.

Possible? surely.  Easy?  Doubtful.   I believe Qt has a nifty generic 
drawing context setup that allows you to use GL as the rendering surface 
for any Qt widgets.  And I bet someone has ported Scintilla to be a Qt 
widget.  So that's a possible existence proof.  But it will not likely 
be easy to duplicate that.
