Yes, you said without agar etc, but I wouldn't give you much of a success rate. So:
If you think you made a very specific and super special cross, you might want to find a flasking service for Orchids in your area.

If you are able to work in a sterile lab environment, and try your hands on doing it yourself, you might wish to google Knudson, Orchid germinating mix, and do some reading on how to flask the seeds. I don't think it is that difficult to do and heh, why not try it.
If you didn't make a special cross and you simply played around for the fun of it, you might consider doing it nature's way before we used sterile conditions by hoping that your well established medium contains the correct fungal thread to nourish any emerging seedlings and simply sprinkle the ripe seeds on top of the medium. Years ago I played around with different mosses ( collected on logs in forest) and soil from native Orchids as a medium, but I was never successful. I see a lot of seed pods on my Orchids, especially when growing outside, but I always remove them.
