QF date rule in "text" field and/or calendar popup

My users really hate working with multiple popup boxes for inputing dates. So I need to create a custom rule to validate a date put in a "Text" field, probally in mm/dd/yyyy format. Or ideally have a text field with a button next to it that triggers a popup calendar. There are multiple GPL pop-up calendars, http://www.dynarch.com/projects/calendar/ being my favorite, but I'm not sure how to implement this popup jscript calendar (or any other one for that matter) and/or have the date validated in a text field. I've been pouring over the examples that come with QuickForm but apparently it's not enough for me to figure it out, any help would be appreciated. Thanks, Keith
