I'm sure this can be done as a custom widget using pangomm or cairomm
(or librsvgmm) to do the drawing/text rendering, etc.  I've not done
anything like this myself but it doesn't sound difficult to do.  There
is a chapter in the online book on custom widgets that could help in
this aspect though possibly someone else might be able to offer you
something they've done that is similar to what you're asking about:
