Hi Brandon,

One possibility to make a custom JDialog is to create acustom JPanel
with all the bells and whistles that you need and use that as the
Component in one of the static JOptionPane functions. Please see the
following example for a dialog that is similar to an inputDialog but
allows multiple text areas for user input.
