There are a number of applications that can normalize audio.  From the
command line the lame mp3 encoder can increase the gain and do some
basic EQ tweaking.  mencoder is another command line option.
normalize-audio is yet another command line tool for this job.

On the GUI front audacity is the application that most closely resembles
sound forge.  Under the "Effect"  menu is a normalize option.

It should also be noted that audacity will run under Windows as well.
