You can use one of the usual suspects for debugging an exe on Windows, Visual Studio or WinDbg. Using the debugger of choice, start debugging tshark.exe in the wireshark-gtk directory of your build environment, set the arguments to the debugee (tshark) as required, you may need to point the debugger to the source file location, set breakpoints as required and you should be up and running.
