Yes, you can change the default OS by editing the grub menu.lst file. You can edit it from Ubuntu using the gedit program. To do this, press alt-F2 and enter the command
gksudo gedit /boot/grub/menu.lstFind the line near the top that says
default 0Make sure you have the line without the # at the start. Change the number to the number of the Windows menu item, starting at 0. So if the Windows item is the fifth, change the default argument to 4:
default 4Then save the file, and reboot. It should automatically boot Windows.
If you change the argument of default from a number to the word saved, the default menu item will be whichever you used last, as long as that item has a savedefault entry in it. See the Gnu Grub manual (http://www.gnu.org/software/grub/manual/grub.html#default) for details.

Keith, if the OP's menu.lst has the automagic parameter # updatedefaultentry=false, which I think is the default, update-grub will undo his new default setting. See this thread (http://ubuntu-utah.ubuntuforums.org/showthread.php?t=809163). If the OP wants to keep the XP as the default OS, then he should set # updatedefaultentry=true before upgrading to a new kernel, or doing update-grub.

I bow to your superior knowledge, I dont have a windows installation just some spare partitions that i use to try out different distros and i edit my grub menu.lst by hand (when i install a new distro I dont install grub I edit the menu.lst and then do update-grub from a rescue partition).
