AFAIK, there's no implementation of CAPI other than Lispworks.  
It doesn't seem to be a free software library.


So if you wanted to use CAPI on CCL, you would have to implement it
anew.

Implementing GUI with CCL can be done using the Objective-C bridge and
Cocoa objects.

I'm sorry, but I learned Objective-C before lisp, so it's painful to me
to use Cocoa without the Objective syntax.  So I implemented a few
reader macros, and I can do:

    (ql:quickload :com.informatimago.objcl)
    (objcl:enable-objcl-reader-macros)
    (let ((alert [[NSAlert alloc] init]))
      (unwind-protect
           (progn
             [alert addButtonWithTitle:@"OK"]
             ;; [alert addButtonWithTitle:@"Cancel"]
             [alert setMessageText:@"The sum of 3 and 4 is 7."]
             [alert setInformativeText:@"Ain't it great?"]
             [alert setAlertStyle:#$NSWarningAlertStyle]
             [alert runModal])
        [alert release]))

Just use: https://developer.apple.com/library/mac/navigation/
