Domain-Driven RAD Frameworks

I'm half done with the tutorial for AppFuse. So far, it's not much different from the way Butch and I did our last application, only there's already some pre-existing code. I haven't gotten to the part that introduces AppGen, however, and I think that AppGen is the key advantage of AppFuse.

I got distracted, however, by Trails. Check out this movie! You can focus on your domain and the app generates everything front and back of it, both UI and persistence. The stack it uses is Spring, Hibernate and Tapestry.

What I'd like to see is one of these domain-driven RAD frameworks that makes use of the Hibernate-Spring-WebWork-FreeMarker stack, with Java 5 Annotations. And maybe one using Maven instead of ANT?

And I wonder how hard it would be to create a framework that generates a thick client, such as one built on Swing or SWT/Eclipse-RCP.

A framework built on the stack we like might be a good project for O&B, and perhaps something we can open-source. Next on my study queue would be Hibernate Annotations - I found this tutorial.
