I got an assignment in my university. I need to write a single web page, that lists all the classes in the particular web app. Selecting a class, the page should list all the functions in it. Selecting a function, the user should be able to feed the parameters and displayed the returned value as a string.

Now this is the problem statement, hope it is unambiguous. Can some one tell me how should I go about it? Like where do I start, what are the things that should be considered and so on. Thanks in advance.
