I think you're right about Google not accepting WEBDAV write operations, 
and their gData protocol is definitely the way to go for now.  The 
g-client code I mentioned is an Emacs lisp library providing integration 
with a variety of Google services including Gcal.

You can download it from it's svn repository:

http://emacspeak.googlecode.com/svn/trunk/lisp/g-client/

And there is a google group for the project here:

http://groups.google.com/group/emacs-g-client/
