Work from something simpler up to what you need.
As one line, I got the else clause to work like this:
PipeRead 'if [ -r $HOME/.fvwmColors ] ; then fg=`cat $HOME/.fvwmColors | cut -f3 -d" "`; bg=`cat $HOME/.fvwmColors | cut -f4 -d" "`; else fg=AntiqueWhite bg=RoyalBlue; fi; echo "echo *FvwmButtons: Fore $fg"; echo "echo *FvwmButtons: Back $bg"'
Watch the semicolons.
I didn't test too carefully, to leave you some fun.
