.bin file in linux. How to stop and how to create executable icon for use in GUI.

I downloaded Zotero, an app for document management. I downloaded the standalone version for linux. The download supplies a folder and the folder has shell script, zotero, and an executable, zotero-bin. I searched and found that I can start the executable with Code:./zotero-bin. When I execute that command in the terminal, the app runs fine and the terminal keeps a blank line after Code:./zotero-bin It won't let me type anything in that blank line. And more importantly, I don't know what to type to get Zotero to close when I'm done with it. I know I can use CTL-C or or -Z or something to stop the zotero-bin, but I don't know if that's the correct way to stop the program's execution. What should I do to stop/close an executable when I started that executable in the terminal?

Also, is there a way to create GUI icon so that I can click on that icon/shortcut like I do for most of the other apps I use, like clicking on the Firefox icon or OpenOffice icon to start those respective programs?

I'm working with Slackware 14.2, but this question is relevant to any newb on a linux distro.
