Python rasterized or rendered (two different methods) to screen thru Blender would probably be the most productive.
Either Python or C# is basically newber friendly.
OpenGL or Direct3D are APIs that take time to learn in order to display 3D to screen, but if you are willing to turn your "experiment" into a dedicated hobby more long term, then you will get nice results.
There really is no quick and easy way for a beginner to make a complex coding which displays a 3D object to screen, unless you are talking extremely simple coding and object. There are some tutorials online about making console applications which are generally the simplest coding to do the job. We are not talking applications for video game consoles but console applications that use the very basic computer functions underneath to do what you want. You need to literally start much simpler than 3D and work with 2D for a while. Start with "Hello World" console application and build on that.
