Yes, it's possible.

First of all, you'll need a GPS receiver (either built into the computer, or connected to it).

Typically, GPS units use a simple text protocol to talk to the host over the serial port. There are plenty of libraries out there that can help you if you don't want to parse the protocol yourself; just google "gps java".

Lastly, bear in mind that typically GPS units don't work indoors since they require an unobstructed view of the sky.

First you need to have at least a GPS device to receive the GPS information! Usually, devices are connected through USB, serial port, or Bluetooth. Interface with the device (read the manufacturer's reference book on that). Once you start getting the information, all you have to do is to parse the data and adopt to your program accordingly!
