Build me a Gmail Chrome Extension

I need an extension developed that will create a checkbox in the Gmail compose window. The checkbox needs to have an small icon/logo to the left of it.

The functionality needed is:

1. When you mouse over that section, the popup tooltip should say 'Send Encrypted'

2. When the user hits the Send button, if the checkbox is checked, append the subject line with the following string: ' [Private]'

3. When user hits the Send button, if the checkbox is unchecked, send as normal.
