Radian is an open-source application launcher which centres your favourite and frequently launched applications around your mouse.
All you have to do is right-click on your desktop. This will open Radian, which is circular in shape and divided into quarters and rings. You can customize Radian so that each sector of the circle is filled with the application you want, to the background you want, etc.
Each of the quarters can be a designated custom slice where you manually create the short cuts — a quick launch which will pull from the Windows’ quick launch bar, a desktop slice which will display frequently used desktop short cuts, or a recent documents slice.
