Any sentence with "Easy" and "Writing Games" in it is an oxymoron.
Building games, in particular 3D games with complex engines, is one of the hardest things to program. Game programmers are, by far, the best and most educated programmers anywhere. If you are struggling with C++, you can look at Python, Java, or C#. However, most concepts will be exactly the same in any language you choose, and frankly, you'll need to master C++ anyways if you plan to have a future in game programming.
Also, you'll need extensive education in Advanced Trig/Geometry, and of course Physics.
You can also download Unity3D for free which is a very good 3D Engine that you can build games on. It will give you a taste of how much work goes into building a game, even when the hardest part is done for you.
