I think you mis-read that application note--- it does mention a PC, but not until section 3. And everything they're doing with the PC you can also do with the AVR. The general idea behind what you are trying to accomplish is to establish a serial connection between the GSM modem and the AVR microcontroller, and then write a program in the AVR that sends AT commands to tell the GSM modem what to do. Those commands include establishing a voice or data connection, send an SMS, and so on. PCs of course can send AT commands, especially with the help of programs like Hyperterminal or minicom. There also exists some code for AVRs that can generate AT commands, but you'll probably end up writing your own so that it's more integrated with the rest of your application code. You might also want to look at the avrfreaks forums, there might be some code in there as well.
