Raymond, Look at the (online) Zope book. Chapter 10 is wat you need. http://www.zope.org/Members/michel/ZB/ You don't have to read all of the chapters before 10, chapter 10 is starting in a very basic tempo. However, you'll need to invest some time to study the other chapters if you want to make more of your application.
