Could we do without nib eventually?

Yes, but maybe 2000 lines of code is needed:
(comparing to FLTK)

If there is no nib file then it seems one
must create their own top level window and
process event handling (using NS... obj-C API),
and draw text and/or geometry (using CG... and CT...
C++ APIs ) at minimum.

Well, we will have to do those anyway...

Rather than end up writing a stand alone app
(even using theide), I think it makes sense to either
a) fit new MacOSX code into the Rainbow framework,

Sure, obviously. But I guess you might now be a little bit cofused about Rainbow by "Framebuffer backend".

Rainbow is a compile time method how to replace GUI backend in U++ without tampering with CtrlCore. Framebuffer is an example of such relacement backend.

MacOS X will be another such replacement backend (and perhaps, after fully developed, we will move it to CtrlCore anyway).

All in all, right now, creating "nib-less" cocoa "Hello world" and then making it to compile in theide still makes the most sense as the very next step...

what's the correct way to send the events into UPP?

from fl_cocoa.mm
window & application events:
- (void)windowDidMove:(NSNotification *)notif;
- (void)windowDidResize:(NSNotification *)notif;
- (void)windowDidResignKey:(NSNotification *)notif;
- (void)windowDidBecomeKey:(NSNotification *)notif;
- (void)windowDidBecomeMain:(NSNotification *)notif;
- (void)windowDidDeminiaturize:(NSNotification *)notif;
- (void)windowDidMiniaturize:(NSNotification *)notif;
- (void)windowWillClose:(NSNotification *)notif;
- (void)anywindowwillclosenotif:(NSNotification *)notif;
- (NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication*)sender;
- (void)applicationDidBecomeActive:(NSNotification *)notify;
- (void)applicationWillResignActive:(NSNotification *)notify;
- (void)applicationWillHide:(NSNotification *)notify;
- (void)applicationWillUnhide:(NSNotification *)notify;
- (id)windowWillReturnFieldEditor:(NSWindow *)sender toObject:(id)client;

device events:
+ (void)prepareEtext:(NSString*)aString;
- (id)init;
- (void)drawRect:(NSRect)rect;
- (BOOL)acceptsFirstResponder;
- (BOOL)acceptsFirstMouse:(NSEvent*)theEvent;
- (BOOL)performKeyEquivalent:(NSEvent*)theEvent;
- (void)mouseUp:(NSEvent *)theEvent;
- (void)rightMouseUp:(NSEvent *)theEvent;
- (void)otherMouseUp:(NSEvent *)theEvent;
- (void)mouseDown:(NSEvent *)theEvent;
- (void)rightMouseDown:(NSEvent *)theEvent;
- (void)otherMouseDown:(NSEvent *)theEvent;
- (void)mouseMoved:(NSEvent *)theEvent;
- (void)mouseDragged:(NSEvent *)theEvent;
- (void)rightMouseDragged:(NSEvent *)theEvent;
- (void)otherMouseDragged:(NSEvent *)theEvent;
- (void)scrollWheel:(NSEvent *)theEvent;
- (BOOL)handleKeyDown:(NSEvent *)theEvent;
- (void)keyDown:(NSEvent *)theEvent;
- (void)keyUp:(NSEvent *)theEvent;
- (void)flagsChanged:(NSEvent *)theEvent;
- (NSDragOperation)draggingEntered:(id < NSDraggingInfo >)sender;
- (NSDragOperation)draggingUpdated:(id < NSDraggingInfo >)sender;
- (BOOL)performDragOperation:(id <NSDraggingInfo>)sender;
- (void)draggingExited:(id < NSDraggingInfo >)sender;
- (NSDragOperation)draggingSourceOperationMaskForLocal:(BOOL)isLocal;

Sounds pretty much similar to Win32/X11. Coresponding files in CtrlCore are Win32Proc.cpp and X11Proc.cpp...
