I am trying to put together a panel which needs to consist of 20 lines,
each containing :
JLabel - 2 columns
JTextField - 1 colomn
JTextField - 1 column
JLabel - 2 Columns
The JText fields would be filled out from arrays, so it would be layed
out with the help of a 'for' loop.
I put together a test program (provided below) to try to emulate this,
but the layout manager only seems to want to give each entity (JLabel,
JTextField) the same amount of width each regardless of what I specify
in the GridWidth fields. Can this be done with specifying sizes for the
individual JTextfields or labels? Please advise - Thanks - Lou

    //pane.setPreferredSize(new Dimension(300,200));
   
    for (int i = 0; i<3;i++)
    {
        label = new JLabel("test");
           c.gridx = 0;
