While it's true that GNUstep app wrapper support does not provide any 
mechanism for the wrapped non-gnustep apps to open URLs on behalf of the 
GNUstep workspace (so you currently have to write a service to invoke 
the appropriate binary to open a URL), that's mostly because the wrapper 
support in GNUstep pre-dates the Cocoa/Apple APIs for opening URLs, 
rather than any technical problem.

So I have created a branch of the gui library (named 
app-wrapper-open-url) with code to implement opening a URL using an app 
wrapper, so you can try that out if you like.  Basically, when opening a 
URL rather than a file, the script in thew wrapper is invoked with 
-GSOpenURL rather than -GSFilePath,  and the info plist needs to contain 
the information about the URL schemes supported (example in the 
NSWorkspace class documentation after the example ofusing an app wrapper 
to open a file).
