If the target will run it, .NET would probably prove pretty good. You've got a good selection of languages, and even the de facto standard of C# is actually pretty decent (well, I think so anyway - has all the things I liked about Java, and mostly fixes most of the things I didn't). And if you need to write bits in C/C++, that's not a big problem, because the FFI is very easy to use. (MS's long-term plans for .NET always seem a bit of a mystery, though, and Mono never seemed to get much mindshare. Probably nothing that a bit of your $100,000,000 budget couldn't help with...)
