UI/Dialog for presenting data in popup from db, then editing in place - ??


I'm trying to figure out the right plugin to use. I am presenting the
user
with a schedule - they will click on a date and I'd like a popup
window to
come up. The popup will be populated with volunteer slots for that
particular date (pulled from a mysql db). If the user wants to add
themselves, they'll click on an Add button, add their data, save, and
close
the window.
Is UI/Dialog the right tool for this type of thing? Or am I better
off
going with jqModal or plan old js? Anyone have any opinions on this?
thanks...
