Nintendo used the official Nintendo SDK for DS / 3DS, obviously.
It heavily depends on the game making tools you're using. Different utilities and programming languages may do it in different ways, if at all.
If it's meant to run on a PC on seperate monitors, I'd guess DirectX and OpenGL would have some functions to get that set up. If it's meant to run on a single screen on a PC, but in two parts, you'd use two different rendering views, but draw them on the same output. I'm not experienced with the technical aspects and coding of such things, though.
