A Good Intro to wxpython/PostgreSQL Applications?

[PAllen]

Hi all,

I am trying to get rid of a few of my old MS Access applications and
move them to PostgreSQL and Python/wxpython.  Does anyone have any
suggestions on the easiest way to learn to program small database
applications with python & wxpython?  Does anyone have a few small
examples at least?

I will mainly need forms with/without subforms for viewing and
inserting data into the database.  Nothing too complicated to get
started.

thanks,

Phillip Allen
