Wordpress developer

I'm creating a school website and wanted to create a plugin with source code doing: 1- add a school to the admin menu with three basic submenus: subject, student, teacher. 2- Create custom tables called Subject, Student, Teacher 3- Add/Insert/Delete subjects, teachers, students to/from custom tables created in step 2 4- Teacher interface has a name, address, email, telephone, and optional short description text area. Students almost the same as teachers, and subjects interface has a subject name, subject code, subject teacher. Thnaks
