Development [Java] Layout Manager Trouble

I've been fiddling round with layout managers for a while and can't quite get it to sit the way I want. I figured it's probably something simple but I can't quite seem to see it, so I thought someone else might be able to look at it with a fresh pair of eyes

The basic jist of it is that I have a frame with multiple containers on it. It's an order form and I have a container panel that includes 2 JLabels and corresponding JTextFields where the user would type the quantity they wanted.

I first tried a basic grid layout and that does almost what I want but the size of the text field is stretched to mirror the size of the item label. I want the text field to be a set size which is independent of the label.

Does anyone know how I might do this?

Code:

// SQUASH RACKET PANEL
        JPanel squashPanel = new JPanel();
        BoxLayout squash = new BoxLayout(squashPanel,BoxLayout.X_AXIS);
        squashPanel.setLayout(squash);
        
        squashTitle = new String("Squash Rackets");
        squashBorder = BorderFactory.createTitledBorder(squashTitle);
        squashPanel.setBorder(squashBorder);
        
        string1 = new String("Racket 1 (£000.00) Code xxxxx");
        string2 = new String("Racket 2 (£000.00) Code xxxxx");
        
        label1 = new JLabel(string1);
        label2 = new JLabel(string2);
        
        field1 = new JTextField();
        field2 = new JTextField();
        
        field1.addActionListener(this);
        field2.addActionListener(this);
        
        squashPanel.setLayout(new GridLayout( 2, 2, 5, 5));
        
        squashPanel.add(label1);
        squashPanel.add(field1);
        squashPanel.add(label2);
        squashPanel.add(field2);

 

Looks to me that you need GridBagLayout.

In essence you'll need to swap the gridwidth between 1 and GridBagLayout.REMAINDER
So something like (and I'm just doing this from memory so it may not be 100% correct)

Code:

JPanel pnl = new JPanel(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.anchor = GridBagConstraints.EAST;
gbc.gridwidth = 1;
pnl.add(label1, gbc);
gbc.gridwidth = REMAINDER; // Puts item at end and forces a newline
gbc.anchor = GridBagConstraints.WEST;
pnl.add(textbox1, gbc);
gbc.anchor = GridBagConstraints.EAST;
gbc.gridwidth = 1;
pnl.add(label2, gbc);
gbc.gridwidth = REMAINDER;
gbc.anchor = GridBagConstraints.WEST;
pnl.add(textbox2, gbc);
etc.....
