Google are an OpenID provider.
To login with a google account you need to use openID
Google Docs on their implementation: http://code.google.com/apis/accounts/docs/OpenID.html
It could be easy to solve if you use library that implements open ID for you.
Use the Google OpenID API (as this site does)
