ACL for groupfolders

Hello, I would like to know if exist a way to do achieve this:
-Create a groupfolder called GFold;
-Create a Folder called #1Folder inside GFold;
-Create two folders inside #1Folder, called ToRead and ToWrite.

How can I set the right combination of ACL to this child folders to permit to user I share to read only on the ToRead folder and to Read/write/delete on the ToWrite folder?

Anyone can help me??

Thanks a lot!
