Navigation based upon user answer to question

I want to build navigation based upon the answer that the user puts in for a number of questions. Kind of like a tree as how the navigation goes.

Is there a wiget that does this already, or do I need to build my own?

Example:

The question is male or female?

Goes to page a information if male, page b information if female.

Next under a information, if 35 and under or over 35

goes to c informaiton if 35 and under and d information if over 35

Thanks
