Yes What I am trying to say in my previous mail is this:
L1 L2 L3 L4
TF1 TF2 TF3 TF4 Add
When "Add" is clicked, becomes this:

TF5 TF6 TF7 TF8 Add
TF9 TF10 TF11 TF12 Add
and so on....

Hi

The conventional approach is the one I looked at and it is what seems
more desirable ... However I tried experimenting with your program to
change the addColumn to the addRow method

private void addRows () {

constraints.gridx=fields.size();
constraints.gridy = 0;
panel.add(new JLabel(labelText), constraints); // I took this out
because I didn't want the labels to appear repeatedly when user
clicks ..
JTextField field = new JTextField(6);
JTextField field1 = new JTextField(6);
JTextField field2 = new JTextField(6);

constraints.gridy = 1;
constraints.gridy=1;

You need to increment gridy once for the new row.
You need to adjust gridx for each field.

panel.add(field, constraints);
panel.add(field1, constraints);
panel.add(field2, constraints);
fields.add(field); // so we can later retrieve content
fields.add(field1);
fields.add(field2);

Maybe you should consider a for loop involving an integer variable x?

   y++;
   constraints.gridy = y;
   for(x=0, x<3, x++) {
      constraints.gridx = x;
      JTextField f = new JTextField(6);
      panel.add(f);
      fields.add(f);
   }

I suspect you don't really need the extra variables x and y, you could
just operate on constraints.gridx and .gridy directly. But it seemed
clearer to have x and y.

Perhaps fields should be JTextField[][] instead of List<JTextField>?

panel.revalidate(); // redo layout for extra column
}

However the problem is that it still keeps adding one textfield though
columnwise and not rowwise...Besides I removed the InputDialog as that
was not needed for repeated and new labels in the main program (The
actionevent method)

I couldn't figure why it kept on adding columnwise and not rows ??

constraints.gridx and .gridy set the x,y position of the component:

0,0 1,0 2,0 3,0
0,1 1,1 2,1 3,1
0,2 1,2 2,2 3,2
etc
