Add a "which product is best for me?" filter.

I'd like to create some sort of guide for customers to determine which product is best for them. This would be a series of simple yes/no questions which would lead through a logic tree.

Two questions:

- Has anyone got a good method for doing this?

- I'd like to add a link somehow in the store that would say "Which product is best for you" and lead to a page with the above-mentioned questions.  Product pages seem to be populated only with product, so I wonder if there is a way to do this?

Thanks!
