[Spout] Show Inventory made with InventoryBuilder on Popup screen?

I'm not sure if this is even possible but I'll give it a try.
I've created an Inventory with this code:

Code:java

Inventory inv =  SpoutManager.getInventoryBuilder().construct(player.getInventory().getContents(), "My awesome inventory!");

player is just a regular Player.
Now the problem is showing the screen to the player because I dont wan't it to show up like a normal Inventory, I'd rather attach it to a GenericPopup I made. I doubt it's possible to just attach it straight away, my guess is you have to make a for loop like

Code:java

for(ItemStack itemstack : inv.getContents()) {
                // DO stuff
            }

and for each itemstack you'd create a Button and an ItemWidget and do some stuff with those.
So if anyone has a quick solution for this or have some time leftover to try and create something like it, then I'd be glad

 

How complicated it is depends on how many itemstacks you're talking about, and whether you want them to appear in specific positions. Basically , though, you fill a popup with the widgets you want, then attach the popup to the main screen.
