Script or Application Needed - PHP - Easy

I would like to have a simple script or a mini windows application completed that will: 1. go to a url 2. input a username/password 3. Then once logged in will simply click a link inside of the account. I would require that it allowed me to input multiple username and password accounts and be set up to run once per day. Whether Cron jobs were used, or a web interface to control the once per day query it should be simple, allowing a time of day to run. A simple admin that would list the account to manage and allow adding or removing. I hope to spend $15 or so on this project since it is very basic.
