is there something similar to Cocoa in Windows?

'Cocoa' is Apple computer's implementation of 'Objective - C', on the Macintosh (PPC and Intel based) platform.

'Objective - C' is available for a variety of Operating Systems.

A 'Google' search produced this one (of many) related link.
 
Cocoa is Apple's evolution of OpenSTEP. NeXT ported older versions of OpenSTEP to Windows NT. Cocoa, like OpenSTEP and NeXTstep before it, is written in Objective-C, the object-oriented version of C developed by NeXT.

Well, as has been pointed out NeXT/Sun ported the NEXTSTEP APIs to Windows NT (and Solaris) in the form of OpenStep Enterprise. NeXT/Sun also made the OpenStep Specifications open for anyone to use... which has led to the GNUstep project.

Apple was planning on providing an application environment on Windows based on OpenStep Enterprise called Yellow Box for Windows. Even though Apple only released Yellow Box for Windows bundled with the Rhapsody Developer Releases, the application environment in WebObjects 4.x is actually Yellow Box (note that Yellow Box used both Objective C and Java). Apple subsequently removed Objective C from WebObjects in version 5.

So the question comes up... what do you want to do with it?

If you would just like to play with it... then WebObjects 4.x would be a good starting point. You can get WebObjects 4.0.1 here for $30.

If you wish to create apps for others to use, then GNUstep on Windows would be a better choice (though you won't have the same type of Apple developer tools to work with).


I have screenshots of Yellow Box on Windows NT 4.0 Workstation (here) and Windows 2000 Pro (here) and WebObjects 4 on Windows NT 4.0 Workstation (here) if you wanted to see what those environments look like.
