building a new programming language like the ones you see in GameMaker software or scatch requires deep understanding of Window's binary code. This is not something you can finish in a few years, it takes maybe 10 to 20 years to completely make a new code language. If you only want to make it for games you still have a long way to do it since many of the important software like Geforce will not accept unknown language. This problem as been a thing since Linux and no one has still found a stable version for such.
I recommend not creating a new code language without help of at least 10,000 people, any one else would just go learn C, C++ or HTML/CSS.
