Build a Grabcut software.

Have u ever done Grabcut application? I want to extract a foreground image from a given image. That means remove background image from it. I need to open several images at once and need to remove their background and get the main foreground image and save them. If anybody has source code, it will be better. If u have, u have to show it via teamviewer, and if I like it, I will buy it.
