Basic Crafting System (Minecraft Style)

Hello there everyone. I am currently working on a survival project and i was wondering if anyone has any idea on how to make a basic crafting system like minecraft. Nothing spectacular, just basic enough so you can put two or more items together in a uniform grid panel or something in a UMG widget to created another item. If you have any ideas and or know how. I am willing to pay to get it working. Thanks for your time!

networked. i currently have an array set up for the inventory im using i just cant think of how to make the two work together
