Yep Chad is right, You haven't missed the point of GWT I just don't think you understand the scope of GWT. Think of it as kindasortbutnotreally the same scope of Jquery. All front end interaction (client) and helps you communicate with the server (whatever server/language/framework that is)
Using GWT-RPC helps communicate with a java servlet Just to give you an example, I have a full GWT app (Di with GIN, MVP and all that jazz on the client) I use GWT-RPC to communicate with a java servlet My java servlet talks to my Data Access layer which is all wrapped by Spring Framework GWT -> GWT-RPC -> Java Servlet -> DAO -> SpringJDBC -> Postgres/MySQL/ Oracle/etc hope this adds some value...
