Yes, you can play on the same computer the server is being hosted on, provided of course, you have the hardware to do so. I only have experience running servers on remote hosts, so I can't help you in setting up a server on your computer, well at least not the port forwarding part of that.

Assuming you want to run a server on your own computer, you should start by creating a folder where you want your server files. Then install forge to that folder and create a start up script and save it in that folder. Then, run the startup script. It will probably tell you to change the EULA to true, so do that and add your mods, make changes to configs etc, and then run the script again.
