 Congrats! You've made your very own GUI with Java's Swing GUI Toolkit. This is just the beginning of the possibilities of what you can build with Java; Games, forms, and image displays are now possible with Swing!

 Be sure to check out 
 - [The Swing API Documentation](https://docs.oracle.com/javase/7/docs/api/javax/swing/package-summary.html) to see other methods and objects you can create for your GUI
