    Default Java GUI not working

    I am doing a project for my CSC class and I am having an issue with it.

    The program is suppsoed to accept inputs for cost of an item, 2 different down payments, interest rate, and amount of years for a loan.
    I created to program successfully without a GUI, but I am creating a GUI for it for bonus.

    I am using Netbeans form creator.

    I am unsure of how I am supposed to get the inputs to calculate and display in the correct fields.

    Here is what I have so far.

    PHP Code:
    /*
     * To change this template, choose Tools | Templates
     * and open the template in the editor.
     */
    package midterm;

    /**
     *
     * @author Owner
     */
    public class GUI1 extends javax.swing.JFrame {

        
            /**
         * Creates new form GUI1
         */
            public GUI1() {
                initComponents();
        }

                
                    long   downPayment1, downPayment2, price, fixedPrice1, fixedPrice2;
                    int    rateType;
                    double time, months;
                    double totalPrice1, totalPrice2, monthlyPayment1, monthlyPayment2; 
                    double interest1, interest2,  numTime, interestRate, numberCompounded;
                

                
                
            /**
         * This method is called from within the constructor to initialize the form.
         * WARNING: Do NOT modify this code. The content of this method is always
