Yes, I believe custom project guides require programming. Assuming
you are using Project 2003, there are a series of articles named
"Project Guide 101" which are included in the help file
pj11ProjectGuide101.chm that is installed with Project.
The Microsoft download center also has additional information. Try
searching the download center for Project Guide and I believe it will
take you to a download containing sample code.
I'm afraid I can't give much more information on the "how-to" side as
I am not a programmer. If you are interested in pursuing further
details, try posting to the project developer newsgroup.
I hope this helps. Let us know how you get along.
