How to choose the right GUI toolkit ?

BTW: I did a search and found the testnotebook example from:

http://prdownloads.sourceforge.net/pythoncard/testNotebook.zip?download

and tried it out.  There is one error in the widget.py that I have to
get around.  Changed from:

        canvas.setFillColor('gray')

to:

        try:
            canvas.setFillColor('gray')
        except:
            pass

and then ran it.   Works!

So, yes, you can do Notebook in Python.  I believe what they are saying
is that Notebook isn't supported fully (yet) in the resourceeditor.
