There are some great and big mods which have interface to select items:
EfficienSee
Helmod
and maybe others.

These mods have buttons which allows you to select an item.

Can you expose this button and corresponding dialog to be used in other mods?

They are just normal sprite buttons - when clicked, they simply put an item stack in to the player's cursor (or take what's in the cursor and put it in the sprite button).
