Datawindow inside a datawindow

I'm wanting to create a datawindow, that has a child data window with multiple records.

I have a person record... that has notes assigned to the person.

I'd like the notes to have multiple records.

I will store the user entering the Note / Deletion flag / date entered / text note

my original person record will look similar to this

With the notes area to look something, like below.

I think I did something like this before, but I can't remember it. 

Is it possible to do this?   can you point me in the right direction?

will it be difficult to maintain the updates on this.   Sometimes, we've done pop-up screens that would do some of the detailed updates
