I totally agree about using a framework.  You say you want a 'simple'
3 page website.  Why do you think it is simple?  You say you don't
have any skills at creating websites with python.  From your
description, you will need to build a directory of entries, a form,
and attach it to a database, so that means you also need to understand
sql (or something!). You need to display individual records I imagine.
 Do you need to edit them after they are created?  How are you going
to manage the accounts?  Will you create them?  Will you let the
visitor create an account?  Where will you store the account
information?  Do different accounts have different permissions?

If you install django (for instance), go through the online tutorials
in about 2 hours, you could probably build your specification in a
day.  Even if you have problems there is an active django mailing list
to ask specific questions.  I haven't tried the other frameworks, but
there might be similar help available for them.
