Whoa! Have you looked at the Expenses sample app in GWT trunk? It runs
on GAE with the App Engine Datastore.
GWT-RPC or RequestFactory let you easily make AJAX calls to any
servlet-based services, and how you implement those services is
completely up to you.
As far as debugging, you certainly can continue to use hosted mode
debugging while deploying server-side code to an external server. See
