creating an XCode project with existing code

Question

I'm in the process of porting a Linux application to Mac. I have different files with the source code that can get compiled and linked using the standard Makefile.

I'm going to be porting that code to Mac and continue writing code in C (sorry, no obj-c). Is there a way to create a project on XCode, add the existing code so I can use XCode and the IDE, compile and debug the code and generate Mac Makefiles?

Thanks for the help
