Hi! There are a couple of different ways to go about it. If there is wiring in place, with the power off, you can switch out one fixture for another. If there is no wiring there you might consider a plug in light that you can hang.
Here's a link to what I mean. Hope it helps:

Are you wanting to have a light fixture on the ceiling where there already are electrical connections, or where there is presently no wiring installed in the ceiling?
If the latter, then the only option is to have a swag style fixture that plugs into the nearest electrical power outlet via a long cord.

It’s not clear to me if you actually want to do wiring & build entire fixtures from scratch or what, sorry.
Please get a pro involved if you’re dealing with live electrical wiring and not just painting or putting a different globe on an existing UL Listed light fixture.
If you want to do something like make a fabric or paper globe or something that has the potential to get hot because of the lightbulb’s emitting heat, think about how to mitigate that fire hazard.
