Get Item default Warehouse from stock with Custom Script

Hi there.

I need to figure out, how to get an Items actually Warehouses if the Item is in Stock.
In other words, when I list the Item i Need to link the warehouse with a read only Field to this Item like on the Dashboard in the Item head section.

So please let me know how can I do it.

I think I need to create a Link Field that fetch the corresponding warehouse.

Please let me know.
Thanks a lot.
