Yes... make your text into an image with a transparent background (or a .bmp with a solid black background will work, too)
In your script, load up the text as a HUD. When the player is within range of picking up the weapon, have it display the text HUD you loaded and also fade it out on the same line.
Now also check for the player pressing the needed keyboard key to pick it up and when they press it while in range, have it pick up the weapon...
Those are my tips for you. We don't take requests, so I'm doing the best I can by hinting you in the right direction.
I suggest reading some scripting tutorials and learning to script. It's not very difficult and it's sure better to make your own scripts than to wait on people to make them for you.

Those who live in the past, are destined to insanity. Those who live only for the future, will be slaves to their ambitions.
Those who live in the moment... only they, are truly happy.
