None. I'd use Go with standard library templates and plain ol' CSS with a sprinkle of JS.
If I was forbidden to use that, I'd probably use Ruby on Rails, Django or something like that.

Is it possible to build “nice” websites like that?
I have made a number of fully profitable (and pretty nice) websites over the last few years using that stack.
I can't point to any specific resource for learning how to do it other than the official docs regarding writing web applications [1]. For me, it all started there and evolved over time.
