Hi, I'm going to write a program that is to be integrated with word and I
don't quite know where to start. I've been fiddling with VBA for a while but
there are too many limitations. I need to know what tools will make the task
easier.

- It should be possible to fire via a word toolbar.
- I need to use functions that are obviously used internally by Word but
that I can't find in the VBA docs, like the _correct_ word count as opposed
to the one described in the docs that counts newlines and punctuation. I can
write my own, but prefer to use what already exists.
- I need to package the program nicely so it's easy to install.

What tool(s) will be more helpful? Should I go with .NET? Which programming
language? I know C++ well, and some VBA. Perhaps C#?

Any pointers will be greatly appreciated!
Thanks :-)
