Develop a custom Wordpress plugin for subscriber's address entry

I would like to develop a custom WP plugin that has the following: 1- User side (page): - a form that starts with a google map where user can select where his house is - couple more text fields for user to put house number and other information, just text fields. 2- Admin side (page): - a page to view users submittals (pending status) and approve address or reject. The status is reported back to user by email. - if approved, a list of all users entries can be viewed (list of users, when user is clicked, all information is shown on a page) - status of an entry can be changed from rejected to pending or approved or vise versa and the change reported to user through email. 3- DB table that has one entry for each user (once submitted) and a column for status 1 active 2 pending 3 rejected. The plugin should have custom theme files so that language and text can be easily changed and edited. Development in English language, but will be translated by us to Arabic afterwards.
