If you can write it directly you can create from Objective-C.In there nearly everything explained. Here

But If you want to create in Javascript,HTML.There is a application Appcelerator Titanium Which you can develop the application in Javascript and HTML.You can look here to see a chat example with Titanium.Also Titanium converts code the objective C at the end.
