This Python code defines a Welcome class that creates a GUI window using GTK and Glade. The class loads a Glade interface file, gets references to the main window and a label, connects signal handlers for window closure and a button click, and shows the window, hiding the label initially. When the button is clicked, the label is shown, and clicking window close quits the main loop.
