Google Friend Connect makes it easy to enhance your web site's social and viral features, such as member management, message board, reviews, and picture-sharing. All without programming!
To add Google Friend Connect to your web site you just need to add a few lines of code in your web pages where you want the gadgets to appear.

Your visitors will be able to login to your site using their Google, Yahoo, AIM, or OpenID account.

And connect with their friends from Facebook, Google Talk, hi5, orkut, Plaxo, and other OpenSocial enabled applications.
Sharing is also easy as it is also possible to invite friends (and friends-of-friends) from their contacts without leaving your site.

Google Friends Connect hasn’t been public released since it is in development phase, but you can sign up for a preview release.
