After a quick search over Internet, it seems that there are plenty of similar applications that have similar functionality. However, it seems that most of them are developed using PHP programming language. You can use this or any other language that suits you and can do the job. It seems that the latest version of Dreamweaver can work with PHP, so it's possible that you won't need any other tool for creating the service. The application that you try to develop is an application that searches and provides for strange behavior of the hosts. Also, the application should be able to work with messages, so it's advise to use a database to.
Before you can start the developing process, I strongly suggest that you use Google in order to find out more about this type of tool and what functions might need to be implemented.
