There are complete java and gnu C grammars for ANTLR (a parser
generator) at www.antlr.org. I've used ANTLR heavily for several
years and find it ideal for language implementation. Tree generation,
manipulation and traversal are some of its most useful features.

You might want to take a peek at Supercollider (www.audiosynth.com),
It's a Smalltalk-ish language for audio synthesis that uses some
interesting paradigms for building processing structures
programmatically.
A particularly neat feature is that most of it (including garbage
collection) can run at interrupt time.
