         final JTextField Textbox = new JTextField(16);
    	 JFrame frame = new JFrame("Java app");  
    	  JButton button = new JButton("Send Command");
    	  JPanel panel = new JPanel();
    	    frame.setSize(500, 400);

    Are there any error messages? Please copy and paste them here.
    To see the error messages, open a command prompt window, go to the folder with the jar file and enter:
    java -jar YOURJARFILENAME.jar

    Then copy the contents of command prompt window:
