Create a very basic C# form with given code

I have a scrambler code in C# which basically accepts some text from user and produces a scrambled text. That's Encryption.. Then user asks to decrypt and we give him back what he typed earlier. This code is available with me. (Its also available on internet) What I need to do is create a Form. Create a some buttons and text boxes which will do same thing as above. Make a button that says "Encrypt" On clicking we get a text box where user types a text. In the label a scrambled text is displayed... For e.g.. if he types abc we get pft ... Reverse way there is second button which says "Decrypt" its text box accepts "pft" as input and sends out "abc" as output.. That's all the form does....
