I am fairly new to Office development, and I would appreciate advice on what
approach/technology would be most appropriate for my situation.

Here is a summary of what I am trying to accomplish:
- I need to modify a single Excel document that will server as a template.
- I need to add controls (buttons) to the document that will initiate
certain actions.
- I do not want to create an add-in that will be available for any Excel
document on the end-user system.
- .NET is preferable.
- End users will mostly have Office 2000 on Win2k

My current understanding is that the options a
- VBA
- .NET Add-in (if possible to constraint for a specific document)
- .NET Microsoft Office System Project

Any comments are appreciated.
