To Go or not to Go?

Apparently Go language makes more and more community attention. Today made a 15 min try and was surprised how simple and fast you can get into it.
Surprisingly, there is bindings for GTK which allows to write GUI apps for both Linux and Windows, and one of the demos looks as simple as:

package main

import (
	"os"
	"github.com/mattn/go-gtk/gtk"
	"fmt"
)

func main() {
	gtk.Init(&os.Args)
	window := gtk.Window(gtk.GTK_WINDOW_TOPLEVEL)
	window.SetTitle("GTK Table")
	window.Connect("destroy", gtk.MainQuit)

	swin := gtk.ScrolledWindow(nil, nil)
	swin.SetPolicy(gtk.GTK_POLICY_AUTOMATIC, gtk.GTK_POLICY_AUTOMATIC)

	table := gtk.Table(5, 5, false)
	for y := uint(0); y < 5; y++ {
		for x := uint(0); x < 5; x++ {
			table.Attach(gtk.ButtonWithLabel(fmt.Sprintf("%02d:%02d", x, y)),
						 x, x+1, y, y+1, gtk.GTK_FILL, gtk.GTK_FILL, 5, 5)
		}
	}
	swin.AddWithViewPort(table)

	window.Add(swin)
	window.SetDefaultSize(200, 200)
	window.ShowAll()

	gtk.Main()
}
