Or you may search on github for terms like "gtk cairo", there are some
hits.

Such a widget would be nice, but I know that it is much work to make a
really fine one. You intend to use plain C? A Questions is, if cairo
drawing is fast enough in all cases. For my app 
http://ssalewski.de/PetEd.html.en it is fast enough, but I tried hard
to draw new only what is really necessary. (And it is not only slow
because I choosed Ruby language, performance is really restricted by
cairo, but maybe I will be able to further improve performance.)

You may also have a look at 

https://gitlab.com/ivor/GTK3-Cairo

it was recently mentioned on gtk-list, but I had no time to look at
that one.
