To add a program to the Quick Launch area, you can right click the program in the start menu. You'll then another menu appear. This one:
Select More from the menu above, then Pin to taskbar from the submenu. You'll then a new icon appear on the taskbar. In the image below, we've pinned a piece of software called NetBeans to the task bar (the blue cube on the end):

If you want to remove a Quick Launch icon on the taskbar, right click the icon and select Unpin from taskbar:
