Hey LittleMissChatter,
You're too late for Sept 2010 sadly, they are very strict about the deadline, and interviews will be beginning in about a month; so already shortlisting for interviews and offers will have begun. If you sent in a form it wouldn't be considered.
Because Queens doesn't operate through ucas for nursing theres no means of gaining a place through clearing as nursing never enters clearing, theres a waiting list for places for each intake of people who are suitably qualified for entry so thats why they don't.
If you want specifically to go to Queens your only option would be to apply for Sept 2011/Feb 2012, childrens only have about 30 places for nursing so its very very competitive.
I would recommend if you want to study nursing next year to apply to one of the scottish universities, you could even do an adult nursing course and do a postgraduate diploma in childrens nursing once you qualify.
I was in the same position you are but I was lucky enough to get in before the deadline last year. Good luck with whatever you do and if you have any q's ask away.
