I built exactly that a few years ago: V8 with WebGL bindings that passed through to OpenGL ES. It was to enable WebGL experiences on the GearVR, where a full browser wouldn't cut it.

I've got sample using an OS X window but it should be easy enough to do the same for Windows

It's been sitting in a private repo since then but I can give you access if you'd like

That being said, I think a better alternative for a thin graphics scripting environment would be haxe with Lime or snowkit (which provides OpenGL, SDL and windowing). I've used these in the past and loved working then
