[Zope] How could I do it...

Hi! I want to rewrite a simple ZPublisher banner exchange to a Zope app. I'm new to Zope and I don't know how I could to it. What I need is a way to create user accounts (need not to be Zope users) which different fields. A new user should submit a HTML form with password, name, email, etc. and a ne user account should be created (user object?). The user should be able to modify or delete his user account data.
