Swing/AWT/SWT :: Option Buttons Goes Into SelectionValues Argument

public static void main(String[] args) {
String[] images = new String[5];
images[0] = "B.png";
images[1] = "M.png";
images[2] = "H.png";
images[3] = "D.png";
images[4] = "S.png";

[code]....

There is my code so far, on the line JOptionPane.showInputDialog(null, "Give us a word starting with "+text[i]+":", "tut", 2, image, ?, null);, eclipse gave me 2 extra arguments following the icon and I'm not sure what exactly goes into the 2nd to last, the "selectionValues" argument.

After checking the Java docs, it was apparent that the option buttons goes into the selectionValues argument, but is there a way to work past that if I would only like the default (OK, Cancel) buttons on my window? The school haven't taught us the method to create custom buttons and I doubt I would've been set something that was not taught.
