Create Dialogue Box
 

This is what I want to accomplish but I do not know how. I am new at this.
In cells D-I, I want to be able to click on the cell and bring up a dialogue
box that consists of a list of checkboxes, which I can check off as
completed, tasks if you will. I would also like the option of a comments box
as a part of this dialogue box.

If you can understand at all what I am trying to get at, I would also need
pretty explicit directions in doing this.

I hope you can help and I thank you in advance if you are willing to explain
this to me.
