You should really use the |*ProcessBuilder 
<http://docs.oracle.com/javase/7/docs/api/java/lang/ProcessBuilder.html#ProcessBuilder%28java.util.List%29>*(List 
<http://docs.oracle.com/javase/7/docs/api/java/util/List.html><String 
<http://docs.oracle.com/javase/7/docs/api/java/lang/String.html>> command) 
contructor, that will give you more control on the parameters and let 
you avoid a lot of quoting and escaping. And instead of calling  Gimp, 
make it call a small script/program that dumps its parameters to stdout. 
As far as I can tell you are using the Unix shell syntax (leading single 
quote) while the file names indicate you are on Windows...

You will also save you a lot of grief by making all your scheme code a 
small script. Once that works you can try to pack the whole script back 
in a parameter.

If you call gimp with -c you will get messages printed to the console 
(ie, stdout) instead of being displayed by the graphical UI
