        tk.Tk.__init__(self)
        self.attributes('-alpha', 0.0)  # make window transparent
        # build gui...
        self.after(0, self.attributes, "-alpha", 1.0)  # back to normal
root = MyTkRoot()
root.mainloop()

Here's a reference to the code with the example of a Toplevel. It will also work with the root however.
