How to debug and build an iOS version in Windows 8.1

Guys,

I have an android app done, and I would like to build an iOS version. But I do not have any ios device nor notebook ou desktop.

So, my question is how can I do do have the same Android environment to be able do test, debug and build a iOS version, using Windows 8.1

Is there any emulator/simulator for that ? Will I need to install a virtual machine with Mac OS ?

Thanks,
Marcelo.
