How to apply an effect on screen image in Windows on the fly?

问题

I'm developing a Windows application that needs to apply an effect on screen image. More specifically, I need to do the following: grab a screen image, apply a gaussian blur on it, and display it on the screen. Something similar to f.lux, only in my case the effect applied is different.

Since I'm new in Windows development, I'd like to know what is the recommended way to do it? What libraries/frameworks should I use? Can you point to some code samples of similar applications?

Thanks!
