Game Maker
It is a simple program for making games for Windows, it can make about any 2d game you want, and can do some 3d if you have the pro version (but it isn't too great at 3d), it can also do online too with pro.
With it, you don't even need to learn to code, as it uses a system of dragging and dropping icons as a alternative.
Here is a video displaying what kind of games it can make.
