I suspect you mean Ada. It's a woman's name, not an acronym.

What, precisely, do you mean by "PCs"? It used to mean "something
running Windows". Now it can mean "cheap, generic x86 hardware,
running some popular OS". But given the Macintosh, it can mean "cheap,
generic x86 or PowerPC hardware, running some popular OS".

Yes. There are Ada compilers for lots of "PC" targets.

Or some other OS that runs on the target (Windows, Lynx, VxWorks,
Apple OS X, BSD, etc).

I don't think VMS has been ported to anything other than VAX and
Alpha. Of course, there is "cheap, generic Alpha hardware" that runs
VMS; can you use that?

What windowing system does your application use (if you have a GUI)?
What OS services does it require? From your statement above, I can only
conclude that it needs networking. Does it use TCP/IP sockets, or some
VMS thing? Of course, given a modern processor, you might be able to
do everything in one processor, and get rid of the networking.
