Not without using a "true" explorer shell (e.g. XPE or similar). Having a shortcut on your desktop requires 2 mouse clicks. Only one click required for your Geoshell quick-launch taskbar.
You can modify your taskbar by examining
geoshell.inf and making the appropriate changes. I think you'll find it's not difficult - besides, it's gratifying to figure it out on your own... so I've pointed you in the right direction - good luck.
