Custom widget for StringListProperty in GAE

Question

I am using StringListProperty to store series of steps/tasks. By default StringListProperty is having Textarea widget. Instead i want to have multiple Text input fields each one for each item in the List.

1. Is this something that is possible in GAE (or atleast in Django)
2. Can the same be wrapped into a custom property such as TaskListProperty

Any inputs are warmly welcome :). Thanks in advance.
