I'm making a python script that should run in the background and notify a user of changes, and I'd quite like it to work cross-platform. Main problem is, I don't have access to a mac at all, so coding specifically for it could be very difficult. wxPython seems like massive overkill for simple popups, so is there anything with a lighter footprint?
Does Python on Windows and Mac also ship with Tk wrappers? If so, you might be able to roll your own notification box. I do not think they have a dead-simple notification API (i.e. you pass it a string and a cute box pops up for 5 seconds) however at least you will only have one codebase to maintain.
I am thinking about other cross-platform apps such as Skype, Dropbox, and Thunderbird. Skype and Thunderbird seem to have rolled their own, and Dropbox went the platform-specific route.
