Keylogger Builder

Question

Hi ive made a keylogger in C#. But it is only  the server file. So if i want to change my email to where the logs will be sent, i need to manually edit the code and then recompile.

Question: How do I make it such that it is sort of a keylogger builder. Where i can enter the email address/password, logs interval in textboxes.Then when i hit the create button it should create the keylogger server file for me.

I heard it has to deal with stub file. Can you guys explain what it is and give me a code example with it. 
Example code could be like: Enter a name in  a textbox and hit create button-->output is a new exe file with the name in the Label.
