Just create a new method that you connect to your button's clicked()
signal and include the Exif extraction code there. Since your Exif
extraction already seems to be in Python, you do not have to execute
any external programs.

connect(yourButton, SIGNAL("clicked(bool)"), yourExifMethod)

The signal is documented here:
