PHP on an intranet with MSOffice-like templates

(originally posted to php-db, but I realized that this list is far more germane for the question - apology to those reading it twice). I don't even know if this is possible, or if I'll have to go the route of .NET development to get this sort of functionality (I'm sure it's possible if I jump through enough hoops). But here's what I'm trying to accomplish... - users are all on a local intranet with access to a shared drive (no prob) - users navigate a PHP-MySQL application to select records from a database (no prob) - users are able to click a link which will launch some sort of document (they have Office, but if something like PDF is available on a Windows platform, great) where a document template is fetched and updated with information from the selected record. (This is the part I don't understand how to do). An example... user wants to be able to print one of a variety of letters to physically mail to a customer, customized with the customer's account info. (You know: Dear [first name] [last name], ... Your account [account_id] ... is 30 days past due... etc ) This way, management can update the template and not have me re-work the code to have it work... Is such a thing possible on a windows PHP platform? Can someone point me to somewhere I can learn more about it? Thanks much, -P
