Sending command to a robot from a mobile phone with Symbian OS

I want to send simple commands (turn left, right, start, stop, speed 123, etc) from a mobile phone with Symbian OS to a mobile robot.
I have strong C++ experience both in Linux and MSWindows but I do not have experience in SW development in Symbian OS. Can someone suggest how can I start writing apps for mobile phone? Which SW development tools? Demo/example codes for Symbian apps? Is there any mobile phone to/from robot comm apps examples on the web?
