What you'll needAt least 2 wireless adapters. I've got three. First one is the internal adapter which came with my laptop. The other 2 are DLink adapters.
This is what it looks like.

Now since we have multiple adapters, we can use one of them to create a wireless network on Windows and then practice hacking it on a virtual Kali Linux machine. Now here's a detailed guide on how to create a wireless ad-hoc network. I'll just post a screenshot of me doing it right now.
This is our newly created network. Now we can turn on our Kali machine and see if it is discovered there.
So it showed up pretty fine. We can use netsh to modify the security parameters as necessary (WEP, WPA, etc. and practice our hacking skills on our dummy wifi network)
Important Update : I couldn't figure out how to create a WEP network using command line. So if you wanna practice WEP hacking, then this will not help.
