Resources for resource files?

["Orgren, Joseph H" <JOSEPH Orgren associates dhs gov>]

I haven't been able to find a sample resource file, which would show for 
example how to set up styles.

I'm specifically interested in changing the "GTK" cube icon in the main 
window decoration to an icon of my choosing.
