Interesting idea.  The balloon text (see Educational uses in the docs) 
and colored objects could display such functionality on the lilypond side.

This could certainly be automated for notes with a scheme function, 
although you'd probably want to apply this to any notation, not just notes.

For the user interface, I suggest looking at lilypondtool.  It should be 
possible to hack something together with that, and I was amazed when I 
saw the flash demo.  (I even considered giving up vi... for a few 
seconds.  :)
