I played around with it, it is nowhere near Qt, not even like 5% close. Qt isn't just a GUI library, it's everything you need to build a application in a nice large bundle. But it's a nice start...
However I feel that Go is not really intended to be used for desktop applications, I would much rather see a Rust GUI library.
Re:Things from Python I'd miss in Go

Yeah he says "Go's Qt bindings are 'not recommended for any real use'" but he is only linking to a 3rd party library that's [apparently] not ready for real use--I guess he could "there are not yet good Go bindings for Qt", or "the GUI toolkits are less developed than Python's" or "Go has no built in GUI but python does (tkinter)" [does anybody use tkinger anyway?].
Another thing that confuses me here is that he's saying "here are things I think I'd miss if I moved from Python to Go" without ever having done it to see if he actually misses them...[once more familiar with Go, he may end up not missing them as much as he anticipated].
Curiously absent also is a mention of significant whitespace, perhaps he wouldn't miss it? :)
I haven't yet tried this lib, It may not as good as something as Qt, but I think it is a good beginning.
