Is it possible to create a PDF of the current page?

Question

What I want to do is create a PDF document of the current page programmatically.
I have taken a quick look at iTextSharp and it seems that is not what I am after - it looks like you have to output line by line to iText#

What I am looking for is a bit similar to how you may choose File, Print, select a PDF writer, enter some details (eg, filename, etc), but this should all be done with minimal user interaction. In other words, user clicks a submit button on the form, a pdf is created on the server and then sent to the user via email.

Is this possible?
