I have experienced this. I learned that this is a problem with plugin for the wizard requiring libXm.so.3 which was not present on my Fedora Core 5 distribution. You should be able to confirm this if you select IDE preferences "Plugin diagnostics" and set the level to "All". When you start CodeWarrior you may see:
Error: File 'LinuxStationeryWizard_LinuxX86Rel' reports this error while loading: libXm.so.3: cannot open shared object file: No such file or directory
Error: File 'LinuxStationeryWizard_LinuxX86Rel' does not load. The error number is 205006.
Error: File 'LinuxStationeryWizard_LinuxX86Rel' fails to load.
I obtained libXm.so.3 by installing openmotif-2.2.3. It works now.
