hi, If you are looking for a gui for interacting with chicken and  
dont need the objC, Todd Ingalls and I have a JUCE (cross platform c+ 
+)  app that includes Scheme edit buffers with syntax highlighting,  
tab indentation,  and most Emacs keyboard commands for lisp cursor  
motion . It includes a console window with Chicken scheme.

this app is called Grace (for Graphical Realtime Algorithmic  
Composition Environment)  -- its free and you can rip out whatever  
bits you want, say just the editor and scheme support files.

Here is a screenshot of the editor and console window, the console is  
displaying the results of evaling the forms in the adjacent  
"untitled.scm" buffer. (Output in the Console window is color coded,  
green=values, red=errors and brown is standard output. the app runs  
for sure on osx and linux, it should run on windows

Here is a description of the apps scheme binding if you are interested:

here are directions for building the app:

best,
