I use Ubuntu with Gnome Classic theme because it has more simple looks than latest default Unity theme. I love simple. It also can reduce graphical load in my computer. When I use this theme, some modern features are removed such us feature to create desktop shortcut. I can't drag and drop or make a link an application icon from application menu to desktop directly.
Here is the way how I create desktop shortcut in Ubuntu with Gnome Classic.
1. Open Ubuntu directory explorer and go to /usr/share/applications
2. Find your application that you want to be displayed on desktop
3. Copy your application file to /home/<your_username>/Desktop
|copy Ubuntu application shortcut /usr/share/applications|
|paste Ubuntu application shortcut to /home/<user>/Desktop|
