Build a simple page in wordpress with affiliate marketing links

I need the page to be used for affiliate marketers. They need to be able to add their affiliate id code to the URL and have the links on the page also populate with the same affiliate link... Example: [login to view URL] and the links on that page populate with the link url and AFFILIATEID123 so many people can use the same page and get credit for sales. I dont need design, just the plugin and setup to make this work
