This is really basic stuff but I just can't seem to get my brain to
function; a poke in the right direction would be really useful!

I'm writing a BlackJack class and I'm just putting together the game
itself. I'm sure you're all familiar with the rules, but essentially
I'm using an JOptionPane to ask the user to twist/stick and then doing
so based on their input. My problem is then asking them to twist/stick
again once they've clicked twist, without just nesting if statements. I
know there's an easier way but I'm damned if I can remember.. here's my
code:

   DeckOfCards newDeck = new DeckOfCards();
   HandOfCards newHand = new HandOfCards();

   newDeck.shuffle();

   //deal two cards
   newHand.addCard(newDeck.pickNextCard());
   newHand.addCard(newDeck.pickNextCard());

   //show 'em what they've got in their hand
   newHand.display();

   if (newHand.isBust() == false)
   {

     JFrame frame = new JFrame();
     Object[] options = {"Twist", "Stick"};
     int choice = JOptionPane.showOptionDialog(frame,
                                               "Would you like to
stick or twist?",
                                               "Blackjack Game",

JOptionPane.YES_NO_OPTION,

JOptionPane.QUESTION_MESSAGE,
                                               null,     //don't use a
custom icon
                                               options,  //the titles
of the buttons
                                               options[0]); //default
button title

     if (choice == JOptionPane.YES_OPTION) {
       // User clicked twist.
       newHand.addCard(newDeck.pickNextCard()); //deal another card
       if (newHand.isBust() == true)
       {
         System.out.println("You are bust!");
       }
       else
       {
         newHand.display(); //show them their new hand
       }
     } else if (choice == JOptionPane.NO_OPTION) {
       // User clicked stick.
       newHand.display(); //show them their closing score
     }
   }
