You're surely right for the OpenID part. If you use appEngine as a backend, see this article for details http://code.google.com/appengine/articles/openid.html, which uses Google as a provider (should work by simply replacing the provider endpoint for other providers).
A well known general library is http://code.google.com/p/openid4java/. This should work well outside of appEngine, and has good tutorials for what I remember (I am on appEngine, so I switched tho their native support). I can't help for the oAuth part, sorry.
