Design Function in Java

So recently I created a currency converter in Java. The GUI was completely done using the design function. I closed the design function and I am wondering if there's anyway to edit the GUI after this, because the code that the design function outputs is definitely odd. Here's the GUI code.

public HorizontalView() {

initComponents();







}







@SuppressWarnings("unchecked")







private void initComponents() {

PBactionListener ButtonListener = new PBactionListener();







jTextField1 = new javax.swing.JTextField();







jComboBox1 = new javax.swing.JComboBox();







jLabel1 = new javax.swing.JLabel();







jComboBox2 = new javax.swing.JComboBox();







jButton1 = new javax.swing.JButton();







jButton1.addActionListener(ButtonListener);







jTextField2 = new javax.swing.JTextField();







jTextField3 = new javax.swing.JTextField();







setDefaultCloseOperation(javax.swing.WindowConstan ts.EXIT_ON_CLOSE);







jTextField1.setFont(new java.awt.Font("Arial", 0, 18));







jTextField1.setHorizontalAlignment(javax.swing.JTe xtField.RIGHT);







jTextField1.setText("1");







jTextField1.addActionListener(new java.awt.event.ActionListener()







{







public void actionPerformed(java.awt.event.ActionEvent evt) {







jTextField1ActionPerformed(evt);







}







});







jComboBox1.setFont(new java.awt.Font("Arial", 0, 18)); // NOI18N







for (int x = 0; x<148; x++) {jComboBox1.addItem(StringArray[x]);}







jLabel1.setFont(new java.awt.Font("Arial", 1, 18)); // NOI18N







jLabel1.setText("Converts to:");

jComboBox2.setFont(new java.awt.Font("Arial", 0, 18)); // NOI18N







for (int x = 0; x<148; x++) {jComboBox2.addItem(String1Array[x]);}







jButton1.setFont(new java.awt.Font("Arial", 1, 18)); // NOI18N







jButton1.setText("Convert");

jTextField2.setEditable(false);







jTextField2.setFont(new java.awt.Font("Arial", 1, 24)); // NOI18N







jTextField2.setText("Amount...");

jTextField3.setEditable(false);







jTextField3.setFont(new java.awt.Font("Arial", 1, 24)); // NOI18N







jTextField3.setText("$$$p00nz!");

javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());







getContentPane().setLayout(layout);
