Delaying send data until event occurs

Question

Hii all,
I'm new to java socket programing.
i'm trying to develop simple system using TCP socket for client server communication over a network. I use AWT for user interfaces.
The client program is supposed to get two inputs from user via 2 Text fields and send those to server.
In my client program i have a method to listen server socket send data to server and inner class for user interface thing and i have called those 2 in main method consecutively.
I want to delay calling listenSocket() method until the user click submit button. i think i have to use some synchronized methods but i dont have much idea of how to do it.
I have attached the code here.
Can anybody help me plzzzz? any suggestions would be appreciated.
public class Client {
/*for TCP socket connection*/
Socket clientSocket=null;               
PrintWriter out = null;          
BufferedReader in = null;
private String accountNo =null;
private String accountType =null;
public static void main(String[] srgs) {
Client client =new Client();
CustomerRequestUI requestUI =client.new CustomerRequestUI();
client.listenSockect();
public void listenSockect() {
try {
clientSocket = new Socket("localhost", 1234);
out =new PrintWriter(clientSocket.getOutputStream(),true);
out.println(accountNo);
out.println(accountType);
} catch (UnknownHostException e) {
     // TODO Auto-generated catch block
     System.out.println("Unknown host: localhost");
     e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
     System.out.println("No I/O");
     e.printStackTrace();
class CustomerRequestUI extends Frame implements ActionListener{
          //declare components
          Label accNumLabel     =null;
          Label accTypeLabel     =null;
          TextField accNumText =null;
          TextField accTypeText=null;
          Button submitButton     =null;
          Button closeButton =null;
     public CustomerRequestUI(){
          this.setTitle("Customer Request");
          this.setLayout(new GridLayout(3,2));
          this.setBackground(Color.lightGray);
          accNumLabel =new Label("Account Number");
          accNumText =new TextField(10);
          accTypeLabel =new Label("Account Type");
          accTypeText =new TextField(25);
          submitButton =new Button("Submit");
          closeButton =new Button("Close");
          //add components to frame
          this.add(accNumLabel);
          this.add(accNumText);
          this.add(accTypeLabel);
          this.add(accTypeText);
          this.add(submitButton);
          this.add(closeButton);
          //add ActionListener to components
          accNumText.addActionListener(this);
          accTypeText.addActionListener(this);
          submitButton.addActionListener(this);
          closeButton.addActionListener(this);
          this.pack();
          this.show();      
     public void actionPerformed(ActionEvent event) {
     Object source =event.getSource();
     if(source ==submitButton){
          accountNo =accNumText.getText();
          accountType =accTypeText.getText();
     if(source ==closeButton){
     this.setVisible(false);                    this.dispose();
     System.exit(0);                    
}

If you want to listenSocket after a user clicks submit, why don't to call listenSocket when the use clicks submit.
