You can use the visual editor for Java to lay out Swing components
using GridLayout.
The layout manager java.awt.GridLayout lays out components in a grid
of equal-sized rectangles in rows and columns. You can set the number of rows
or columns that a GridLayout will contain. As you add components, they are
added in order based on the componentOrientation property of the container
that is using GridLayout (RIGHT_TO_LEFT or LEFT_TO_RIGHT).
