1- what is a "VM"?
2- Can a programmer anyone develop one?
3- If the answer is yes, how? And if not, why?

Answer 1

VM "Virtual machines" are used in programming language to make run your code on it to make platform independent, because every operating system has his own architecture and different complier which that every os compile you code in his own way.

So to make the code independent they develop vm to run make the code run on it instead of make each os deal with the code in his way.

Yes you can create a vm you can check this article to know more:
