arduino sends its data through a serial port, so anything that can read a serial port is a good choice. I am partial to C# but any of the visual products will have pretty much the same features. Theres also processing which is java based if you dont want to bother compiling or nailing your application to windows only stuff, but if your just wanting to print values from the arduino, use its biult in serial monitor or an external terminal program like hyperterm or putty.
