Customization of Comments Area in a WP site

Project Description:
I need to customize the comments area in my wordpress. To explain it better, the site is for people who are all waiting for a particular thing (a surgery).
In comments, they will usually say how long they have been waiting. Some people already got their surgery and want to share how long they had to wait in total. I need the comment fields to include a Date Picker, so they can choose the Date when they applied; the lapsed time must be calculated automatically and be displayed on top of the comment, in a small rectangular frame (on a different background color.) There also must be a checkbox saying something like "Is your wait over?" which then displays another date picker, for the user to select the time when they got a response. So, in this comment, the time displayed will be "for a finalized procedure", not "still waiting" and will show up on different background color.
I also need an extra field for their city (and not website, or subject, as in most WP installs - this part is easy.) Note: the lapsed time is calculated and displayed instantly to the user, and not just after moderation.

Example of a comment area:

Select Date DD MM YYYY (Date 1)
Did you get it? Yes No (if Yes, another Date picker is shown, Date 2)
if No, the time elapsed between the Date 1 and the Current Date is shown, in Days, weeks or months, on a yellow background with a clock icon in the corner
if Yes, time between Date 1 and Date 2 is calculated and is shown in Days, weeks or months, on a light-green background with a check sign in the corner

Comment Field

The user can submit JUST the time, and no comment in the text, or JUST the text, and no time.
Ideally there should be the possibility to comment using Facebook, (like in Disqus and such), but this part is optional.

Thank you all in advance.
