Something else

If I knew the Domains SID I could (probably) use SidToName() to find the groups, but I don't want to hard-code any of this information if I can help it.

Actually, the link got me thinking, and a couple of links further on and a bit of searching around led me to the conclusion that I'm not going to be able to get there.

I can get the SID of the groups, but as it is in byte array form there is not much else I can do with it using native KiXtart - I don't want the aggro of installing SDK DLLs on all machine of all the users who will use the tool.
