Are 3d Desktop Environments possible?

I have what i think is a great idea for a VR "Desktop Environment" where instead of everything being essentially the same as on a flat screen with icons and such, files and programs could be stored in more physical ways when using a VR headset. I have exactly zero knowledge of how to get started doing something like this but I want to know before I spend way too much time on this if something like this is even possible. Thanks for your advice.
