Creating a contact list program

Question

I am coding a contact list application in eclipse using Java Swing. How can I get a simple table layout that contains just columns and rows? I don't want row or column labels.

Something like this:

first name: john
middle name: franklin
last name: doe

Where the names would be editable text boxes etc.

What's the best component to use?

I will also have buttons below the text fields. Currently I have a JFrame which is running correctly. It pulls up a window that has my menu options correct. But when I try to do this:

myFrame.setLayout(new GridLayout(6, 2)); 

I get an error. I would like to have a grid layout of two columns and 5 rows (maybe 6). I want to have a label on the left column, and a text box on the right column. then two buttons at the bottom, centered.

You'd better of breaking your fields and controls (buttons) into separate panels, this allows you to supply different layout managers for each.

I'd start with a base JPanel using a BorderLayout.

Onto this, I'd add the "fields" panel at the CENTER position and the controls (buttons) at the SOUTH position.

For the fields, I'd use a GridBagLayout, but I'm picky like that, and for the controls panel I'd probably use a FlowLayout (unless you have access to a nice ButtonLayout manager ;))

This means you could end up with something like

UPDATED with code sample

public class FormPanel extends JPanel {

    private JTextField fldFirstName;
    private JTextField fldMiddleName;
    private JTextField fldLastName;
    private JTextField fldDateOfBirth;
    private JTextField fldEMail;
    private JButton okButton;
    private JButton cancelButton;

    public FormPanel() {

        setLayout(new BorderLayout());
        add(createFieldsPane());
        add(createButtonsPane(), BorderLayout.SOUTH);

    }

    public JPanel createButtonsPane() {

        JPanel panel = new JPanel(new FlowLayout());
        panel.add((okButton = createButton("Ok")));
        panel.add((cancelButton = createButton("Cancel")));

        return panel;

    }

    protected JButton createButton(String text) {

        return new JButton(text);

    }

    public JPanel createFieldsPane() {

        JPanel panel = new JPanel(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();
        gbc.insets = new Insets(2, 2, 2, 2);
        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.anchor = GridBagConstraints.WEST;

        panel.add(createLabel("First Name:"), gbc);
        gbc.gridy++;
        panel.add(createLabel("Middle Name:"), gbc);
        gbc.gridy++;
        panel.add(createLabel("Last Name:"), gbc);
        gbc.gridy++;
        panel.add(createLabel("Date of Birth:"), gbc);
        gbc.gridy++;
        panel.add(createLabel("EMail:"), gbc);

        gbc.gridy = 0;
        gbc.gridx++;
        gbc.weightx = 1;
        panel.add((fldFirstName = createField()), gbc);
        gbc.gridy++;
        panel.add((fldLastName = createField()), gbc);
        gbc.gridy++;
        panel.add((fldMiddleName = createField()), gbc);
        gbc.gridy++;
        panel.add((fldDateOfBirth = createField()), gbc);
        gbc.gridy++;
        panel.add((fldEMail = createField()), gbc);

        JPanel filler = new JPanel();
        filler.setOpaque(false);

        gbc.gridy++;
        gbc.weightx = 1;
        gbc.weighty = 1;
        panel.add(filler, gbc);

        return panel;

    }

    protected JLabel createLabel(String text) {

        return new JLabel(text);

    }

    protected JTextField createField() {

        JTextField field = new JTextField(12);
        return field;

    }

}
