New to Cobalt question

Hi all, I am looking for a way to create something like a task manager of sorts, but bespoke. Can you advise me if Cobalt can help me create something that will operate like this.

1. Each member group is a family (Smith, Jones etc)
2. Each group has multiple users (kids within the family)
3. Each user has their own login
4. The group admin creates multiple tasks with a duration of 1 week (tasks must be completed in the week)
5. Each task is assigned to 1 or more of the group users
6. As a user completes their task, they can upload photographic evidence and select a completed check box
7. Admin of the gorup can go into the system and check a second box confirming the tasks completion
8. Upon the admin box being checked, a value is stored (10 points for example) next to that task and user for the period.
9. At the end of the period (week) admin can look at a report that shows which tasks were completed per user, and the points scored against the taskss.

This is it in a simplified version, but once I can figure this part out the rest will hopefully be easier, and I am hopeful that Cobalt will be the tool to do just this.
