For GPL'd software you can download Windows binaries for cdrecord here
Place these in a directory (I usually create a directory in C:Documents and SettingsduendeApplications) and add it to your PATH (right-click my computer, Advanced Tab, Environment Variables, "New" button under user variables and add the above directory.
Open up your command prompt (Start->Run->cmd) and cd into your directory with the iso.
find out which scsi bus your burner is on with:
(it should give you something like "1,1,0")
Then, burn your iso with:
cdrecord -v speed=16 dev=1,1,0 fedora.iso
This is down and dirty, but it's free. Replace your speed with the speed of your burner.
This may seem confusing, but i love using cdrecord in windows, especially for burning iso's
