Xcode and C++

I have experience with programming Mac when ThinkC was the only option for C++. Recently I have been asked to convert a Windows C++ program to later Macs running OS X. I know that Xcode will compile C++ code, but I wonder how easy and effective that will be.

If I am using Xcode with C++, will I have the advantage of Cocoa and its developer GUI? Or will I be unable to take advantage of the new tools that come with Xcode for programming since Cocoa is written in Object-C? Will I have to develop the user GUI in Object-C which will then (somehow?) call up C++ function code for execution?

In sum, will I be able to integrate C++ code with the Xcode user GUI objects (windows, menus, dialogs, etc.) without having to jump through hoops. And, last but not least, will I have the advantage of using the developer's GUI if I'm programming in C++ with Xcode?

By the way, the Windows code is written in Visual C++ MFC with a lot of old code that's not object oriented.  I'm aware that I will need to strip out all of the MFC and Windows API code and port over just the code governing the underlying functions.

Last, but not least, is software developed for the Mac still tied to the event loop for its overall operation.

Thank you.

Xcode is a great IDE for the C++ project. You can write, compile, debug, etc. It works perfect.

Cocoa is set of frameworks written in Objective-C. It's not C++.
If you'd like to write the standard GUI, it will be easier to use Cocoa.
But Mac OS X projects project may contain Objective-C and C++ code.
Carbon is an older brother of Cocoa and it's written in C (like Win32 API).

There is no MFC for Mac OS. At least not in the SDK's from Apple.

Seems like Qt is the tool that may help:

Thank you for the information and the links. Qt looks like a winner because of the cross-platform capability (Windows and Mac). I wonder, though, how easy it will be to use the Qt platform for designing windows, menus, etc., or if the developer ends up coding most of the user's GUI. Also, surely textedit in OS X no longer has a 32K limit, right? That limit created major problems when I was programming for the Mac several years ago.
