How to make a java swing popup window with combo box and 2 buttons?

http://docs.oracle.com/javase/7/docs/api/javax/swing/JOptionPane.html#showInputDialog%28java.awt.Component,%20java.lang.Object,%20java.lang.String,%20int,%20javax.swing.Icon,%20java.lang.Object%5B%5D,%20java.lang.Object%29 may be good enough if you are willing to leave how exactly the options are presented up to the UI.

I need to make a popup box with with a combo box and a couple of buttons 1) don't use another JFrame as popup window, use JFrame with JOptionPane/JDialog/JWindow these container are same as JFrame, but can take parent and owner 2) don't forget to http://docs.oracle.com/javase/6/docs/api/javax/swing/JDialog.html#JDialog%28java.awt.Frame,%20java.lang.String,%20boolean,%20java.awt.GraphicsConfiguration%29 3) depends if you needed decorated window then use JDialog, don't forget look for setModal() or ModalityTypes, if undecorated then use JWindow 4) don't create lots of JOptionPane/JDialog/JWindow on fly, becasue there Object are still in JVM memory, create this Container once and re-use that (by removing child) for another Action
