  /*
  Obviously, this isn't exactly a beautiful GUI. Learning to make really nice GUIs is an art and
  a Java skill in its own right. We will not spend time focusing on it in this course, but I do
  strongly encourage you to play around with it on your own.

  There are entire books devoted to Swing which will teach you all about GUI layout.
  Many Java textbooks will allocate at least a few pages to it.
