Thomas:

You will only need hex numbers if you want to display the color values
in hex. It is very easy to convert an int to a hex string.

String Integer.toString(int i, int radix);

This sounds like a fun programming exercise even if there already is a
really nice built in tool (JColorChooser) to do the job. Why don't you
start writing it and post your progress and any question?
