Password security system using tkinter gui

I want a gui system using python Tkinter for code given below :
SECURE = (('s', '$'), ('and', '&'),
('a', '@'), ('o', '0'), ('i', '1'),
('I', '|'), ('H' , '#'), ('0','o'),('1','I'),('9','?') , ('u','^'), ('-','_'),('_','-'),(3))

def securePassword(password):
for a,b in SECURE:
password = password.replace(a, b)
return password

if __name__ == "__main__":
password = input("Enter your password\n")
password = securePassword(password)
print(f"Your secure password is {password}")
