Create a GUI with python

I have two scripts of code on python in which first script uses RSA algorithm to encrypt and decrypte an image and the second script uses DNA coding to encrypte and decrypte the image

The GUI must takes an image then encrypte it using the rsa encryption code , then encrypte it more with the DNA , shows the result image ,after that take the result and decrypte it with the DNA and lastly decrypte it with RSA and shows the result which must be the same original image after decryption

The scripts are ready , just to creat the GUI and correctly assign the codes
