from what I've read mercurial is quite easy to use.
1 - Go to the google code link I had above
2 - Log on to your google account (if you aren't already)
3 - Create a new project, select mercurial as the VCS
4 - Navigate the google project web site to get your VCS address (it'll be in the admin section I think)
5 - download mercurial from
http://mercurial.selenic.com/6 - Follow the instructions on the web site but clone from the address you got from google code
7 - program away, check in, push
8 - Come back here and post us a url
If you want to try something really cool, check out
http://hg-git.github.com/ which should allow you to pull from loftar's git repo, into your local mercurial repo, and then push into your google code repo
