How to control servomotor with c# and Kinect?

Kinect

I'm currently working on a c# program that uses Kinect to check the position of a person's hand. It then "moves" an image of a table that is displayed on a canvas according to the person's hand (x,y) to 4 positions: up, down, left or right.
I’d like to know if I can transfer the program I have already created using Visual C# 2010 and Kinect SDK to interact with NXT directly or via Microsoft Robotics Studio.
I want my code to communicate with NXT and activate a servomotor instead of changing the image position on the NUI. Would that be possible?

It doesn't have to be Lego NXT but any other system that would allow me to move servo motors via my program. I'd appreciate any ideas!

e.g: in this code Kinect tracks my right hand and if the conditions are met it displaces the image in Y (for up movement). Instead of that I'd like to know if I can write a code to send a signal to a servo motor via NXT in a not too complicated way.

if (wristRight.Z > shoulderRight.Z - 0.20 && wristRight.Z < shoulderRight.Z + 0.20)
                {
                    if (sideAngle >= 285 && sideAngle <= 320)
                    {
                        speed = 4;
                        positionY = positionY - speed;
                    }
                 .
                 .
                 .

Canvas.SetLeft(Table, positionX - Table.Width / 2);
Canvas.SetTop(Table, positionY - Table.Height / 2);
