I did a project in c++ where the user can encrypt or decrypt a string of text and I need to do a simple user interface, but I have no idea how to do that. Do any of you guys have any tips or tutorials I should look at? (I am a beginner btw)
My idea is to have a box where the user can input the key word for the encryption, if they want to encrypt it or decrypt it and the text they need to transform with the code.

I tried to follow one of the tutorials on youtube, but none of them matched the way I want it to look.
