I recommend using WSGI[1]. That way you can freely switch between
CGI[2], FastCGI[3], mod_python[4], or whatever[5]. It's lightweight and
allows for the use of middleware[6], too. And it's included in python
2.5[7].

[7]: http://docs.python.org/lib/module-wsgiref.html

I would also recommend SQLAlchemy[8], but you may consider that
heavyweight. I consider it well worth it for decoupling the codebase
from one particular database (particularly SQLite), but what do I know.

Finally, you might want to take a look at Genshi[9]. I think web
development is tricky enough that a powerful templating language is
warranted. Most people don't understand proper HTML quotation and those
who do make mistakes. Genshi helps a lot with that. As an alternative,
you might want to look at Brevé[10], which offers a lot of the benefits
of Genshi but is more lightweight and not XML-based (which I know will
appeal to TUNESers everywhere).

I do too much web programming :(
