advice needed for simple python web app

[Dan Perl]

I have a pretty simple python script and I would like to turn it into a web 
application but web apps are a domain I know very little about.  I know that 
Twisted, CherryPy, Plone and Zope exist but not exactly what they do.  I 
need only advice on a direction to take.  For instance a suggestion on which 
application/framework to use would be great.

Basically, what I'm looking for is a web server that accepts an HTTP request 
and invokes a python script.  But I would like a "pythonic" solution so a 
web server like Apache is a solution that I would like to avoid.  The server 
should also be as simple as possible to administrate.

I would be even interested in building a very simple web app server if there 
is a framework that has all the basic components and there is good 
documentation for how to use it.

Thanks,

Dan
