Using GUI to ask user for an alphabet input and to graphically display the hangm

Question

Using GUI to ask user for an alphabet input and to graphically display the hangman.

During each round, the player will enter an input, and the program will display the hangman accordingly to the input.
Main method with a loop that will provide a hint and prompt the user for an input after each round.
String getWord() method returns a random word from our list to use for the game.

Void hangman(String guess) method that will receive the user input as its parameter, see if the input matches one of the alphabets in the word and then print out feedbacks.
Void hangmanImage() that will use GUI elements to display the state of the hangman.
