I highly recommend Andrew Whitechapel's book on .NET development for
Microsoft Office, if you want to go any further than a simple test.

Jordan,

Even a simple COM add-in may raise many problems. You will have to make
the following decisions: what Word versions are to be supported, how
your add-in should react when Word is run via Automation, or in a
container, or as an Outlook email editor.

Look at Add-in Express .NET (http://www.add-in-express.com/add-in-net/)
that provides you with COM add-in development components. We created it
for developers not to waste their time implementing base functionality,
such as: adding / removing toolbars / toolbar controls, event handling
of the host application (Word) or toolbar controls, removing toolbars
and controls during the add-in uninstallation, an so on.
