Adapting the approach shown here to use GridLayout required minimal changes. Also consider BoxLayout, shown here, or GroupLayout, shown here and here.

import java.awt.Component;
import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.GridLayout;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;

You can use a JScrollPane.

All you need to do is instance the JScrollPane class and as the first parameter give it the content pane that is housing all of your text fields.

JScrollPane scrollPane = new JScrollPane(Your main content pane here, ScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);

After that just add your scrollPane to the main content pane.
