Well, life ain't that simple. Getting contributors for an open source project isn't easy. I develop the Virtual Magnifying Glass, with more then 100.000 downloads each year, and even then it's hard to get code contributions. Translations and just building, without developing anything, is easier.
My tips for you are:
* Put the project on source forge, it's free and will call attention to it and showing you are commited with it's open nature
* Make a nice website for it, possibly using the source forge structure
* Make the code accessible on the subversion of your source forge project page, this will make it's development transparent
* On Source forge you can post a announcement asking for someone to port the project. I've already posted several for the magnifier, some were answered, others not.
* Try to announce your project on adequate places, where this is permitted to get people to know about it.
Just saying this is easy and will help a lot of people isn't enougth to get developers. There are lot's of useful projects out there without developers.
