Go for it.
On the arduino side look at the serial communication demos.

On the PC side, google C++ serial port communication. It would be really easy in .net.

For the Arduino side, have a look at the examples in Serial Input Basics - simple reliable ways to receive data. Ideally get the PC program to match the technique in the 3rd example for greatest reliability.
