Hi Nicolas,
Welcome to Javaranch.
I suggest you have a look at
Ruby on Rails. It is a framework based on Ruby programming language, and is creating quite a buzz with its ease of development.
In
Java world, there is
Trails, and a new entrant
Sails. But both of these are probably still experimental. I would not consider these for any real development yet.
Disclaimer - Haven't use any of these in real world, so do your research.
