Another alternative for those too faint of heart for this
approach is to wait a couple of months for ObjectAda for
Windows, which has a pretty simple and clean DLL import
and export capability.  Granted, the product won't be
free, but you'll have more time to spend with your kids.

Of course, I'm biased, but at least my opinion is free.
