See go-bgfx for more information.
GLFW is required to run the examples.
Installing and running the examples is simple, assuming you have your $GOPATH/bin setup in $PATH:
$ go get github.com/james4k/go-bgfx-examples/...
$ bgfx-01-cubes
If you want to see the sources to the shaders used by the examples, for now you should go to the original examples: https://github.com/bkaradzic/bgfx/tree/master/examples.
