When developing Grok we actually tried to not pull in zope.app.* code as 
much as possible, especially to prevent any view code from being 
configured as it could interfere with Grok's idea of views.

My suggestion would be, in order to have something ZMI-like on top of 
Grok, to implement it yourself, in other words, to "port" it. Actually, 
the grokui.admin packages might perhaps be of help to you.
