Awesome
Julia interface to the Tk windowing toolkit.
A simple example
using Tk
w = Toplevel("Example") ## A titled top level window
f = Frame(w, padding = [3,3,2,2], relief="groove") ## A Frame with some options set
pack(f, expand = true, fill = "both") ## using pack to manage the layout of f
b = Button(f, "Click for a message") ## Button constructor has convenience interface
grid(b, 1, 1) ## use grid to pack in b. 1,1 specifies location
## A callback to open a message
callback(path) = Messagebox(w, title="A message", message="Hello World")
bind(b, "command", callback) ## bind callback to 'command' option
bind(b, "<Return>", callback) ## press return key when button has focus
