That would be very easy. Register a listener to the table model: 

table.getModel().addTableModelListener(listener);

Look at the event, if the value changed was from the first column and it was set to false then deselect the checkbox.

Have an actionevent for the top checkbox, and on checked or unchecked, run a for loop to check/uncheck all the checkboxes in the table.
