Can I please have a Python GUI with Tkinter for the Python program below

print() print("Welcome to the Menu-driven Two Integer Rotation Cipher") print() # variable to store all the alphabets letters = 'abcdefghijklmnopqrstuvwxyz' while True: # printing the menu print("Choose one of the three options (1-3), shown below:") print("1. Encrypt a message") print("2. Decrypt a message") print("3. Quit") # getting the user choice choice = input("Enter your choice (1-3): ") # checking the input is digit or not if choice.isdigit(): # encrypting the message if choice == '1': text = input("Plaintext message: ") # getting the shift and checking for valid shift while True: shift = input("Enter size of rotation to use: ") if not shift.isdigit(): print('Invalid input. Rotation step should be an integer.') continue else: break # variable to store the encrypted text enc = '' # for every word in encrypted text for word in text.split(): # for every character in the word for c in word: # if character is in letters if c in letters: # finding the index of 'c' in letters i = letters.find(c) # adding the number of shifts from the index i = i + 2 + int(shift) # adds 2 to initial rotation = 3 if i > 25: i = i - len(letters) # finding the corresponding characters for the index in letters and stored in enc(encryption) enc += letters[i] else: enc += c enc += ' ' print("Ciphertext message: ", enc) elif choice == '2': # getting the cipher text text = input("Ciphertext message: ") # getting the shift and checking while True: shift = input("Enter size of rotation to use: ") # new integerrotation if not shift.isdigit(): print('Invalid input.
