1st: Only females plants produce bud, after about 6weeks of flowering, male plants produce the pollen to make the females produce seeds, which isn't a bad thing to me.However, wiht the males, which produce no bud at all, you can use them for making hash, I'll explain if you ask, cuz' it'sa a long recipe.
2nd: Throwing a shit load of seed off just like that would be dumb, you'd have to at least germinate them and plant them decently, but around this time of year it probably ain't the best idea.
3rd: Hiding the plants isn't quite a hard job, just go into the woods and find a bushy/hidden area and plant away, just make sure they got some light to absorb so they can grow well, mother nature takes care of the rest
Finally: Yes man you can grow weed, anyone can and I have just started growing like 3weeks ago for my first time and I'm doing pretty well at it, and I've never grown anything before, so if I can, anyone can, even dumb asses. So don't worry about it
BTW, the only chance to get a decent grow this time of year is to make a indoor grow.
