Can you elaborate on the google account? Google doesn't force you to join anything for this, it's open source, it just so happens that there's employees dedicated to working on it since it is benefiting Google.
As for the code, Golang is a compiled language, like c or c++. Which means that there is not dropping it on your shared hosting provider. You have to have the ability to compile your applications, and run it from command line. This also means that you do not run it with something like apache, Golang would replace apache with its own built in, high performance http package, which is fully demonstrated in the second video.
For quite a while I've been staring at Golang trying to fully comprehend it, knowing how much this language could empower my applications due to it's concurrent nature (think of c++ but MUCH easier). But I would just stare, dabble in a hello world app and never really understand it. Something just clicked for me a few months ago and I've been loving it since. One of the things I was afraid of was the "lack of documentation" because it is such a new language, theres not many examples on the web like there is PHP. While true, I finally learned how to navigate GoDoc (their documentation) which is incredibly detailed and useful.
