Wordpress | generate unique link

I am turning to Stackoverflow community for a need of critical advice.

It's simple, I want a person to generate a link... and that link will have a button where whoever it is sent to, that person can click yes/no - then return the value.

user 1 > generate link > user 2 > options > return option to user 1

Please can anyone point me in the right direction?

Thanks very much!
