This example demonstrated the use of a layout manager to

The Layout manager here is BorderLayout

// There are more layout managers available. The easiest is
// FlowLayout() which will kee adding components horizontally until 
// there is no more space, then it will continue a row lower.

// Now that you are able to create a GUI let's bind actions to those
// components. Wouldn't be handy? :)
