Music playing and editing system

[Anonymous]

Hi!

I've been thinking about working in a music playing and editing system
which works with LilyPond, as it is asked in GNU Task List.
I'd prefer to write it in C++, is there any problem with this?
I guess the best toolkit to use is GTK+, what C++ interface for gtk+
should I use, Gtk-- or wxWindows?

Thanks..
