Wishlist count and show who wishlist the product

Hi Sifus,
I tried to google around but couldnt find either extension or solution for this.

Opencart 1.5.6

I was wondering if there perhaps a way to:

1. Count total of user who wishlist certain product and show it in product page
2. Show list of who is wishlistd product in product page

Simply put, the idea is something like a facebook like, whenever user like a product, then website will show total who liked that product. Am sure there must be a way? I think thats a start.

Thanks!
