I did something like this in the past in a similar situation.
I have a drop down of categories that has all the valid categories and
an additional category injected as ''New Category''. When you
user selects
the ''New Category'' from the drop down, I display another
textbox (I did
this with ajax call) for the user to provide new category name. In the
controller if this new_category param is detected than a new category is
created first before creating the post associated with that new
category.
