how do i write, or create(via a wysiwyg program) an interactive executable program that has two 3d models stored on it, which will allow a user to do the following:
I don't know of any such WYSIWYG programs that creates executables of interactive 3D models. I think the closest thing I've ever come across is a 3D modeller like MilkShape...but it doesn't create executables, and its just a modelling tool.
my second question is how long would it take to produce such a program for someone with no programming background and what resources are available on the net to teach me exactly how to do this.
At least 2 years. The first year you must learn how to program. You will also have to spend time learning an existing 3D API. You could write your own 3D API, but that'll take another 2 years. I recommend OpenGL or DirectX, if you're using C++.
The second year you will basically be creating the program itself.
