Generating an Excel Workbook with multiple sheets

Since it's been a few months, and 59 people viewed my previous post about generating an Excel sheet with a macro in it, I am going to ask a simpler question:
What would be the general procedure to offer the option to build an Excel sheet with about 15 tabs? A few of these will be only the user's records from a certain table, and others will be the results of a query on a particular table.
How does one hook this to a button or link in the PHPR interface?
There are some PEAR functions that should help - http://pear.php.net/manual/en/package.file...ddworksheet.php
Best,
