Hello, I want to have the jcheckboxes take up most of the screen and the radio buttons just to take up the very bottom line in a (0, 2) format. My code pretty much divides the screen in two equal size sections, top half for checkboxes and bottom half for buttons. How do i make the buttons just take up one line and not half the screen???

thank you
