As mentioned by other posters, Rails, Grails and Django all do the job to a certain extend, the hardest part being to gen the UI that is generic enough, yet flexible. Man, hard is not the right word, it is insanely difficult to achieve this goal. That said, this is what our team set out to do. We just released on github the full client for a new type of CRUD app generator http://github.com/urbien/urbini http://github.com/urbien/urbini focused on mobile web apps. Cloud backend is not open source, but is free to use. Developer creates a Model in Web UI on the phone, tablet or a modern desktop browser, and the app prototype is done. Backbone.js models are generated and are sent to the browser when you point it to your app. Model definitions, templates, views, css, images are saved to appcache and LocalStorage and the data for models are saved to IndexedDB/WebSQL and are automatically synced with the server in background via CRUD. Is that what you had in mind?
