Cool :)

It seems that your installation of PyGTK doesn't have the GtkLabel
class, for some reason. As far as I can tell, that has nothing to do
with Anygui -- perhaps it's a version question. I'm cc'ing this to the
Anygui development list, in the hope that the GTK people there may
have a clue. (Pleace cc answers to Graham :)

To check whether this is the case, you might try the following in an
interactive Python interpreter:

>>> from gtk import GtkLabel

Also, you might want to try to run Anygui with some other back-end.
For example, if you have Tkinter installed, you could do

  ANYGUI_WISHLIST='tk' python 12-01.py

Note that since Anygui 0.2 is still not out (in the tradition of open
source software, it has been delayed quite a bit), you will have to
edit the event handlers to use the form

  def handler(*args, **kwds):
      ...

rather than

  def handler(event):
      ...

(This is described in the Anygui chapter of the book.)

Good luck!
