Centering Radio Buttons in a GridLayout

Question

I am trying to create an application using GridLayout and I don't know how to center some radio buttons. The window ends up looking like:

Here is how I added the radio buttons:

JPanel qArea = new JPanel(new GridLayout(0,5));
...
qArea.add(new JPanel());
    qArea.add(o1);
    qArea.add(o2);
    qArea.add(o3);
    qArea.add(o4);
    while(i<50)
    {
        if (i%5 == 0)
            qArea.add(qs[cq++]);
        else
            qArea.add(buttons[crb++]);
        i++;
    }

Is there any way I can center the radio buttons inside their columns?
