create a webapplication prototype with its documintation

This is a project for the development of a web application prototype (non working!!! ) the programing language might be php, html , sql , java ... any of these ,, the web site can be called "myWishlist" which will enable users to create custom product wish lists so the included products would be purchased from affiliated shops. As explained further, the project will include user membership, product categorization, API for affiliate shops. it will work like that Customer visits site, registers an account and logs in. Upon login he can create a wish list of products he wants to receive as gifts. The products can either be selected from an arbitrary number of affiliate shops or can be described using a text field. When the list is completed the user may choose a unique identifier (e.g. 'myWishList') and give that identifier to his friends. His friends then can visit the same website, enter the unique identifier and can buy any item from the list in the affiliated shops or reserve the items they want to buy. key features: - user registration and login - multiple wish lists per user - many items per wish list - search function withhin the affiliated shops - easy way to add additional affiliate shops - multi language support ImPortant note: i want the prototype very simple and not every thing need to be done exactly .. the main things is the documintation after that (technigal guide, user guide, justification, design) ... you probably need to know about software development process ..)
