GUI generated from DSL

[hovi]

Been using this great library for a few projects already.

Before I start doing something, that someone already did:

Since the DSL in the library is very good, it should be no problem to create nice GUI to allow entering the arguments by non-programmers without command line and using appropriate fields for various types. In my case I will go for java swing, but may switch to html with server side. Has anyone did anything like this?
