I like the notion of fully-automated UI tool, not based on source-code generation, like NakedObjects, JMatter, etc.

XIC has its own solution for that, Navilis, which is a component bundled within Xcalia Studio. The main goal is to quickly validate your business model and the corresponding data access layer (mappings, transformations, etc.). It is a little bit like an object inspector (Smalltalk, Groovy) but coupled with some specific tools and widgets for data access (like a query builder, for instance). This kind of component is critical when following the MDA approach.
