Target has tools to place elements in round patterns, you specify number,  
diameter, angle etc...
In most programs you may find a function to rotate elements a certain  
number of degrees. That can be used to generate points by rotating several  
lines and a circle to give the radius, although here you still need to  
place components manually. You can also try to create a pad component with  
the reference point radius away and then placing several and editing the  
orientation to the proper degrees, if that works in your software.

Last but not least you could always convert the polar coordinates into x/y  
via formula or a pocket calculator.
A spreadsheet program ought to help with this.
