Spawn sprite when player triggers something

[JasonX]

Can i spawn a sprite entity near the player when it presses a button, for example? Do i need to modify the engine or can it be done just with QuakeC?

Like a muzzleflash?

No, like a .spr really. Always facing the camera. I want to make a popup appear in the game world when the players get's near a certain entity.
