Event-driven GUIs, PythonWorks, Boa, wxWindows; future directions of event-driven Python?

Thanks! You give me a lot of good ideas, comments, and food for thought, all of
which are relevant to my upcoming decisions. As you allude to indirectly, and
which I didn't mention in my original post, I would really like to ultimately be
able to use my stuff on the web in web pages readable by standard browsers. But
one step at a time is more than enough ;-)))

I do want to avoid buying Visual Basic or Visual Studio. That's where I draw the
line. I'm really glad that ActiveState is porting Python to .Net, because it's
good for Python and the community, but I do not want to buy into that package.

Maybe you are right, I may just have to dig into Tkinter or wxPython; if so, the
week I'm off on vacation is the right time to do it anyway. But still I must
decide between Tkinter and wxPython, which is a big decision.

I will look into Sun's Forte for java. I will probably want to do a Jython -java
exploration in addition to my main thrust of Python and (Tkinter or wxPython).

If I go with Tkinter, I would always have the option of buying PythonWare's
stuff later, since it is based on Tkinter. I would still like a recommendation
from someone who has used PythonWorks, particularly the gui painter.

If I go with wxWindows, I would have the option of going with Boa Constructor
later. So, my decision between Tkinter and wxPython looms a as large one.

For my web stuff, if I were not into Python, my uses would divide into two
parts. On the one part, some of the stuff I want to do would be eminently
do-able with just HTML and JavaScript. I may well do that  because its just
plain easier in the end. (Maybe DHTML too, but I don't know that yet). But i
really woudl prefer to stick with Python based stuff

The other half of my web stuff will require at least CGI and maybe true server
side scripting. I have opened an account just now with Hoibbiton which allows
CGI but not calls to outside URL's, which I am want to do for some simple but
specific webstuff  to create up to date web links for subjects of interest to
me. Does anyone know of any Python web spider software already written?

I still have not tried Webware or Zope really. Webware sounds more simple and
Zope has the site Hurrah which is $20 per month but exposes Zope and Python
scripts. All of this I learned about on this great list. But obviously I am
going off in too many directions all at once and can not learn all of this in
one short week, even while on vacation and devoting myself completely fulltime
to Python ;-)))

Thanks Dave, for your help!!!
