You can of course connect to motion events and just call
get_iter_at_location() or whatever it's called to see which word you
are on. You can also handle the "event" signal on a tag, if there's a
specific tag on the word.

Should be easy, just handle motion events (and enter/leave events)
and apply colored tags.

Yes I would not use the canvas for this, the text features aren't good
enough.
