Well, I've not used xpalette, but I do have an object that will
create indexed color tables. By default the object contains
a six color table, but you can define your own tables. If you
want to select the colors interactively, then this won't help
you. It will allow you to define a set of colors, then let
the user select from those colors. See

Maybe this will help you, or perhaps you could subclass
it to do what you want.
