[Zope] Newbie: ZClass is what I need?

[Fabio Rolando]

Hi.

I am trying to develop a product and I need to define some kind of object 
having a fixed HTML structure and some extra properties. I have to provide 
users with an interface (into the Zope management console) to create 
instances, type the values for the properties, and browse the local 
filesystem to select the file that will be included into the fixed html 
structure.

In other words when they create a new product they should be given an 
interface where they can put values for properties and browse a file on 
their filesystem. When they press the button the new objetc must be made 
available to readers.

Can I do this using ZClass? How can I embed some predefined contents in the 
ZClass? How can I have the instance to handle some uploadable contents?

Thank you all for your help.
