If you mean "Is there a framework for developing web application in natural language?" - no there isn't.
And not only for web application. The natural language is way too complicated to be understand with no duplication of meanings. The syntax is not strictly defined and so on ... In fact we people have difficult times understanding each other :)
You cannot write a formal grammar on natural language that fits in hierarchy of Chomsky. Even the C/C++ grammar is very complicated. (it's Context-sensitive I believe).
Actually I think that not the programming languages are difficult to understand in fact. The algorithms and the concept of programming, the semantic that those programming languages have is more important.
