project, commissioned 2 servomotors with Arduino

hello to all,
I have an electric car and I would like to order the card with the Arduino.
I have 2 servo motors, one for management and one for gas, and I would like to know what is the program that, with a small window which will display, I can order with the mouse pointer. going to the left of the window, my steering servo turns left and vice versa, and that if I vai top of the window, the throttle servo turns left and bottom right.
thank you in advance sa serai super cool if I have a program that works like this.
