Proper collaboration tools aren't easy either, but there are solutions
like Etherpad. It's open and can be enhanced with plugins, so would a
collaborative text editor with a (possibly autorefreshing) preview from
LilyPond constitute as a GUI for your scenario? No autocompletion
though and no GUI like hacklily.org...
