I am not convinced that you need a web framework with Go. There are a number of them out there but I don't know that they really provide enough value over just using vanilla Go. This one seems pretty immature at the moment - if you are going to use a framework one of the main benefits is a middleware implementation and I didn't see that here.
Here is a good article on some of the different frameworks out there:
