+
+"""This program should display a GTK+ window containing a button and label.
+
+You must add two widgets to the box in the window: a Gtk.Button and a
+Gtk.Label.
+
+The Gtk.Button must show the text 'Change Label'. The Gtk.Label must show the
+text 'Initial label.'.
+
+After you have added the two widgets, you must connect a callback to the
+button's "clicked" signal. In this callback, you must change the Gtk.Label's
+text to 'Final label.'. This means that when the program is run and the button
+is clicked, the label should change its text.
+
+You can find documentation for the Gtk.Button "clicked" signal here:
+    https://developer.gnome.org/gtk3/stable/GtkButton.html#GtkButton-clicked
+
+Don't forget to document any new methods you add.
+
+Hint: Don't forget to call the show() method on the button and label to make
+them visible after adding them to the box.
