Mac OS X as PhoneGap platform

Question

I have phonegap app and I wish to port it to Mac OS X

Is there any similar to phonegap platform that make it possible to build native apps for Mac OS X from web apps.

I also interested in Windows and Linux. I wish to be able to hide app in tray and create dialog windows.

UPDATE

I selected Cordova/PhoneGap that now support Mac OS X. When I asked question PhoneGap had no support on desktop but think change.

You are a little limited in features.
