How to make PDF form

How do I make a PDF form from a HTML page or WORD document like WORD or OpenOffice Document that allows form filling in.

OpenOffice supports PDF as well as Office 2010 and Office 2007 with the Add in from microsoft.

PDF Creator has some features but I am not sure how to fully take advantage of them.

Can someone help with information on how you go through the process of making different types of forms, some that can be filled in or not.
