Python Syntax Highlighting Module

[frikker at gmail.com]

Hello,
I have an idea for a project which involves an editor that supports
syntax highlighting.  This would be for any language, particularly php,
html, css, etc.  I would like to write this program using python.  It
would only make sense to base this upon existing open source code.  My
question is there a python module or examples on how to write a code
editor which supports modulated syntax highlighting?

Thank you,
Blaine
