New subdomain multisite on user registration

I don't know if this is even possible, but would like to get some feedback or a solution if it is.

Here is what I would like to achieve:

1. User decides to register on site
2. On registration form, user chooses a sub domain for their drupal site, this form uses Ajax and checks to see if the sub domain is available. Also user will choose the administrator user name and password for their new drupal site.

3. When user completes registration, I'd like a script to:
A: Create the tables in the database using the selected sub domain as the prefix for tables.
B: Create the folder under the sites directory in the multisite drupal directory
C: Create the custom settings.php file for this site
D: Create a symlink for this multisite

4. On the users profile page, there should be a reference to this users hosted site.

I would like to do this, but I'm not fluent with any coding language. Please let me know if this is even possible before I start trying to accomplish this on my own. Any help is appreciated. Thanks.
