There are two major errors in this code.

1. You can't declare popupwindow as a local variable, because it will be
destroyed as soon as you leave button_clicked. You have do use dynamic
allocation, or make it a global variable or a member of a class.

2. popupwindow is not a child of MainWindow, so you will have to do
popupwindow.show_all() instead.
