Put app on iPhone from Windows, is it possible?



Sorry if this question has been up already. I did a quick search but did not find it.

The question is pretty easy (to begin with): Is it possible to upload an iOS app to my own iPhone (not App Store) through a Windows environment?

We are planning a workshop with a group of 16-19 year olds. They will probably get some used windows laptops, but thats all. No Apple dev accounts and probably no macs. To get them started i would like to put a Hello World app on their on phones at one of the first workshop meetings.
