I do you mean by ‘wrappers’ ?
The only usage of the term that comes to mind is a wrapper for launching 
non-gnustep programs as if they were apps (eg using the openapp tool or from 
GWorkspace).
You don’t need a special programming language to do that … normally it’s just a 
directory containing a text file (Info-gnustep.plist), a tiny shell script, and 
perhaps some images.
You coulds look at the documentation in gnustep-gui, but it’s probably 
quicker/simpler to look at / copy the examples in gnustep svn at 
usr-apps/gworkspace/Apps_wrappers
