About drawing the position of pointable object

Hi, everyone, I have a problem about drawing the position of pointable object, and need your help. I want to draw the position of pointable object directly in the windows desktop, but the MFC, or OpenGL, or Cinder need to create a new window, that isn't what I want. What should I do? Thanks.

I think the two likely approaches are:

Create a full screen transparent window.
Get the desktop graphics context and use that for drawing. I.e: http://stackoverflow.com/questions/1536141/how-to-draw-directly-on-the-windows-desktop-c

Ok, Thank you. But I don't kown how to achieve the desired effect like the Touchless For Windows.

I believe Touchless uses method #1 above. (It is possible the Windows version uses a smaller transparent window positioned as necessary rather than a full screen one.)

Ok, thanks for you suggestion, I'll have a try.
