Question

Hello, I am working on a Java Program for morse code! My program is running great but i need help implementing the JPanel aspect. Please help me modify my program below to add JPanel for the user to enter the Pig Latin into!!!

THANKS!!!

Program so far:

package morsecode;

import java.util.Scanner;

public class Morsecode {
public static void main ( String [] args )
{
Scanner input = new Scanner( System.in );
System.out.print( "Would you like to convert English to Morse (Enter yes to continue or no for another translation type)? " );
String answer = input.nextLine();
if( answer.equals( "yes" ) )
{
System.out.println( "Please enter the text you want to translate into Morse code: " );
String english = input.nextLine();
System.out.println( stringToMorse( english ) );
}

if (answer.equalsIgnoreCase( "no" ) )
{
System.out.print( "Morse to English? " );
String answer2 = input.nextLine();
if (answer2.equalsIgnoreCase( "yes" ) )
{
System.out.println( "Please enter the Morse code you want to translate into English: " );
String code = input.nextLine();
System.out.println( stringToEnglish( code ) );
}
}
}
