Date of birth fields - DropDownList controls

I want to include 3 date of birth fields in a web form using 3 dropdownlist controls, day with options from 1 to 31, month January to December and then year running from 1900 to 2007. Nothing difficult in that.
I'm just curious to see if there's a smarter way of doing it than manually adding loads of ListItems (options). I realise I can bind each control to a datasource, for example, a simple XML file containing all the data for each, but this is again quite a lengthy coding/data entry process.
Is there a way of iterating through the days starting at 1 and stopping at 31, and the years starting at 1900, stopping at 2007 so that I don't have to manually list each one as a new option value?
Taking it a stage further, it would be even better to dynamically grab the current year and list all the years from the current year to current year minus 100.
Any thoughts?
