Well, unfortunately it is impossible to make a portal gun without the mod. Sorry.

The only gun there is on portal 2 is the portal gun which creates the portals. You shoot a portal on white surface, and shoot another portal on a white surface, and you can move yourself and objects through these portals.

You put obsidian in an upright 4x4 design, with the middle empty. Or if you have the portal gun mod first craft the portal gun then right click to fire portal and press g to switch between portals
