I expect this is anything but trivial, but I would like to know what I need
to learn in order to do it.

I have an Excel workbook that I use as a piece of data
importation/analysis/reporting software. It's comprised of six worksheets,
has about 20,000 lines of VBA code and about 30 userforms, and uploads report
data to Access. I'd like to be able to distribute it to colleagues, but for
a number of reasons, I'd like to be able to distribute it as a stand-alone
application that doesn't require the use of Microsoft Office products.

I get the impression that this is possible, perhaps using Visual Studio.Net
and Visual Studio Tools for Office, but I'm completely unfamiliar with these
products. I'm also by no means an expert or professional programmer,
obviously, having taught myself VBA as I went along developing this workbook.
That said, I would like to learn, and would like to know exactly what it is
that I need to know, if that makes any sense.

I've seen a few products that advertise the ability to transform your Excel
books into applications, but I don't have much confidence that all the
funcitonality will be carried over, especially the ability to upload to a
database. I'd rather try to develop the application manually.

Thanks for any input at all!
