I think that I can help since I am having the same problem :)
The best references that I can give you is the GCC Frontend HOWTO at
http://www.tldp.org/HOWTO/GCC-Frontend-HOWTO.html. It is based on a
old gcc, but most of the tree structure still applies.
Two colleges and I are working on a minimal "hello world" front end
for gcc. You can find a alpha version at
http://ltc08.ic.unicamp.br/svn/scheme/branches/hello-world
I also recommend that you take a look at treelang. It is quite simpler
than the others frontends in gcc.
I hope this helps,
