 yep.  Pyjamas.  http://pyjs.org

 in fact, it's _so_ abstracted from html and javascript that i ported
pyjamas to the desktop, using python bindings to glib bindings to
webkit - see http://webkit.org or better:

   http://pyjd.org

  Pyjamas is a port of GWT to python.

how about this:

   from pyjamas import Window
   from pyjamas.ui import Button, RootPanel

   def greet(sender):
       Window.alert("Hello, AJAX!")

   class Hello:
       def onModuleLoad(self):
           b = Button("Click me", greet)
           RootPanel().add(b)

is that close enough? :)  does it look _remotely_ like javascript,
html, or even like it's web programming?  doesn't it remind you of
pygtk2 rather a lot? :)
