I also very much like this idea, as I find writing CUI/GUI code kind of boilerplate, annoying, and often feels like this is sth which could be automated.

In fact, I also implemented a similar idea to automatic GUI generation for my music player: https://github.com/albertz/music-player

I tried to summarize the idea here: https://github.com/albertz/wiki/blob/master/automatic-user-i...

Maybe you have some further good references?
