RESTful API explrer (URGENT)

I need some JavaScript code to test/explore a RESTful API. The idea is based on the Google API explorer. [login to view URL] Please take a look at the attached mockup. That is what I need. In the first version, the elements, operations and fields can be all hard-coded. The answer from the server is RDF. In the first version it would be ok not to parse the answer and just show the raw XML answer. It is ok to use open-source code from other projects, as this is a tool for intern use only. I need this latest by Thursday 4pm, GMT+1. To apply for this job please tell me which libraries would you use? Thanks in advance!
