Frescobaldi (http://www.frescobaldi.org/) works exactly like this. It's 
like a latex IDE but for lilypond. It's quite powerfull and 
multiplatform. I use it exclusively now, it's way better that the bash 
script I used before that more or less rebuild the files when changed.

This way you get the power of plain text and you have an almost 
instantaneous snapshot of the end result.
