I haven't found anything that does this just yet (I'm sure it's
probably somewhere in emacs), and have been writing something like
this myself...

Check Info: Emacs: Tags.  A simple HOWTO on tags is:

1) Run 'etags *.c *.h' in the shell to create a TAGS file (better yet
put it in your Makefile so it's run when the source is updated; it's
fast so it can be run on every rebuild).  If you do this, add 
(setq tags-revert-without-query 't) to your .emacs so you don't have
to type 'y' every time the tags file is updated.

2) Over the variable or function type M-. to go to it's definition.

3) M-* pop's (goes back to) where you were before. 

Check the info manual for more options and advanced tags usage.
Another thing about tags is you can perform completion on them using
M-TAB (which you might have to rebind if your window manager steals
that for switching windows...C-TAB would work just as well)

Hope this helps.
