If you're looking to do WebGL without SDL, X11 or GLFW, you can look at the Emscripten html5.h include, which has "native web" functions for creating a WebGL context, after which you can interact with the WebGL context via functions exposed by the GLES2 headers. See functions emscripten_webgl_create_context() and emscripten_webgl_make_context_current(). Here is one test snippet that does WebGL directly without the other libraries: https://github.com/kripken/emscripten/blob/master/tests/gl_textures.cpp.
