Change variable name of component once declared

Question

Hello,
I was wondering if you can change a variable name of a component so if i had the following declaration of a button like this:
JButton btn = new JButton();can i then change the variable name 'btn' to be 'button' after i have declared it like this ?
Many thanks in advance

ok, you might have a better solution for me actually....
What i have done so far is created a JTabbedPane in one class, i have also created a seperate class with extends a JPanel. This consists of two textboxs and two buttons. Now i want to add this class as a component to each new tab that i create in the other class.
However the problem that i have is the reference name that i give for the textboxs and buttons will be the same for the multiple tabs that i create which i guess will not work.
For example, i create 2 tabs each with one of these instances of this class in each. So therefore there will be two identical buttons with the same reference and two identical textboxes with the same reference.
This is the code for the class that extends a JPanel: (note: i have cut out all the layout code to simplify the code a little)
public class client extends javax.swing.JPanel {
    private JButton Sbrowse_btn;
    private JButton Sbrowseto_btn;
    private JLabel SchosenFile_lbl;
    private JLabel SchosenL_lbl;
    private JTextField SchosenLoc_tf;
    private JTextField Schosen_tf;
    private JLabel SsaveTo_lbl;
    private JLabel SuploadTo_lbl;
    private JPanel jPanel2;
    private JPanel jPanel3;
    /** Creates new form client */
    public client() {
        initComponents();
    private void initComponents() {
        jPanel3 = new JPanel();
        SuploadTo_lbl = new JLabel();
        Sbrowse_btn = new JButton();
        SchosenFile_lbl = new JLabel();
        Schosen_tf = new JTextField();
        jPanel2 = new JPanel();
        SsaveTo_lbl = new JLabel();
        Sbrowseto_btn = new JButton();
        SchosenL_lbl = new JLabel();
        SchosenLoc_tf = new JTextField();
}
