Hi, Lumir

You might take a look at pyjamas (http://pyjs.org).  Using pyjamas, you
can have common code for business logic and also for the GUI on web and
desktop.  The main data transfer/persistence mechanism in pyjamas is
JSON-RPC, so that part of the model can be zope or anything that can do
JSON-RPC. 

If you like wxPython GUI code, pyjamas code is very similar, and there
are examples using PureMVC (http://puremvc.org) in the repository. 

You cannot, at present, use zope.interface to do automatic widget
generation in pyjamas. On the other hand, it is really easy to do custom
widgets and client-side display logic.  You write your widgets and their
behavior in python, not in HTML and javascript.  Styling, however, can
be done with css.

In the eight months since I first experimented with pyjamas
(http://www.mail-archive.com/zope@zope.org/msg31618.html), it has
improved substantially.  Fewer gotchas. More joy.  Worth a look.
