You need to call a JCheckBox constructor.  I'm guessing that you believe
that the:
chkBoxes = new JCheckBox[10];
line created 10 JCheckBoxes for you.  This is not the case.  It simply
defined the bounds of your array.  You need to create an instance of each
checkbox.  Example:

chkBoxes = new JCheckBox[10];
for (i=0;i<10;i++) {
    chkBoxes[i] = new JCheckBox();
    chkBoxes[i].setText(names[i]);
    panel.add(chkBoxes[i]);
}


Hope this helps,
