Setting up the notes programmatically

Question

Hi Guys, 
We are developing a SharePoint 2013 app for a Club.
We have two groups (Coaches, Players) .
As a Coach, I want to setup Notes about a particular player in my team, These notes would be Comments or notes or simple text about the behavior of player and must be hidden from the Player. 
For setting up the notes we need to select the Player (profile) and then these notes(comments) should be shared among the other Coaches and will not be visible to Player him/her self. 
I want to automate the setup notes about a player, What would be best way to do this. I have good programming experience but relatively novice SharePoint arena. 
What is best way to do this? Any comments/ suggestion will be helpful 

Answer 1

You can easily do it by creating a list for notes.
Only the coaches have access to this Notes list.. but none of the players have access to this list.
In this list you can have a column of type people lookup and this can point to a player. the next can be a column for the notes.
You can then create form to edit / add notes to this list.
