Need help with Java application

I am just learning Java. I would like to write an application for server maintenance. We have 10 Dell servers and four technicians. Every two weeks we have to perform several tasks on them: check event logs, check disk space, update operating system and antivirus software and so on. As a database I am going to use Derby. When I start the application it should look like a window where technicians can choose their names and servers on which they are going to work. After that it should give them a window where they can check checkboxes for completed tasks. Can you give me some hints? What classes should I create? I was going to create a server class with the following fields: server name, server model, location. Also I am going to create a main application class. And database connection class. Should I create a Technician class? Thank for your help.
