Pick Up Weapon Script & GUI

I would like to know, how would that work??? cos I know about creating the gui 1st, but the scripts are so hard... so in the gui I'll say "Press E to pick up weapon" or it would be better with scripts, were I could say ("Press E to pick up" ...ToolName... ) so thnx for reading and plz answer... (I'll probably recieve many thumbs down)

Go to the tool and scroll down in the properties box. There should be something that says "CanBeDropped". Check that box and you should be able to drop and pickup the tool.
