Thats not so hard. If you make a new zclass and let zope create
the constructor methods, you have XXX_addForm and XXX_add
in your product folder. Edit XXX_addForm to provide form
elements for your values.
Edit XXX_add to check the values in the request first
and inside the:

<dtml-with "MyFolder.createInObjectManager(REQUEST['id'], REQUEST)">

  <dtml-comment>

     You can add code that modifies the new instance here.

     For example, if you have a property sheet that you want to update
     from form values, you can call it here:

       <dtml-call "propertysheets.Basic.manage_editProperties(
                  REQUEST)">

  </dtml-comment>

</dtml-with>

remove the comments and change the <dtml-call> to the propertysheets
you want to change. The name is Basic if you created a propertysheet
with the name "Basic".
