I hope I have the right new groups.

I want to do this:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwue/html/ch12c.asp,
ie I want my Managed .NET application to be embedded and rendered in
Microsoft Word.  Where do I start?  I know C# and VB, but not C++.  How
difficult will it be?

Thank you.
