No, the whole idea is to provide an abstract interface between the
VTK code and the GUI toolkit, to make it easier to port the code
between different GUI toolkits.  Both the VTK pipeline and the user
interface are coded in python, without an interface builder.

For example, what we have now is a python 'event' object, and we also
have an event handler written in Python.  So we receive an event from
Tk, use the event parameters to create our own 'event' object, and pass
the event to our own event handler.  If we want to use some other GUI
toolkit instead of Tk, all we have to do is add some code that will
translate that toolkit's event into our 'event' object.  

We will be releasing this and a fair bit of other python-VTK stuff
over the coming months, under a BSD-style license.  Hopefully the
release won't interfere too severely with PhD, which I _do_ hope to
finish one of these days...
