I recently put together Glitter (https://github.com/Polytonic/Glitter) which is a basic OpenGL boilerplate that runs on every platform. The only dependency is cmake, so getting started with OpenGL is as simple as generating an IDE project file or makefile and pressing play. No messing with compilers or linkers required. :)

I've spent a significant amount of time learning both OpenGL and WebGL, and I have to say, there is significant value in starting with OpenGL first. For starters, the GLSL compiler is much friendlier. There are also merits to understanding the state-machine from a "C" perspective.
