Well, after banging my head on this for a few days, I was finally able
to get this to work. Here is the correct code to do this:
from Products.PageTemplates.ZopePageTemplate import ZopePageTemplate
zptstr = \
<title>This is a dynamically generated ZPT page.</title>
This sentence <b tal:omit-tag="">should contain no tags.</b>
z = ZopePageTemplate(id=None, text=zptstr, content_type="text/html")
The problem earlier was that I was not defining the method with self so
that it would be bound to the context, hence any references later on to
self threw an error.

Yup, doing that now. It should be up on zope.org in the New User How-to
Much thanks to Dieter Maurer, and hazmat (Kapil Thangavelu) on #zope
(IRC freenode) for helping me out with this.
