What you've given about your app, it could be done with any frameworks, including the builtin template engine of the standard lib (
https://golang.org/pkg/html/template/), with Gowut or anything else.
If you're just starting Go, I would suggest to first stick to the standard lib only, get to know it, and if / when it is found lacking certain features, then turn to external libs.
Having said that, if you are somewhat familiar with Java Swing or Google's Web Toolkit, Gowut might be easy to pick up.
