Has anyone used Apple's SDK to create applications for iPhone?

I have written a few apps. They were very basic and I would never release them to the public. I’m not that confident.

If you have experience with Xcode and Objective C you should go for it. If you don’t know what those two things are you should expect a rather steep learning curve.

And everyone starts somewhere. Give it a whirl. The only thing you lose is some time.

I have made a few widgets with it, I suppse it must be pritty good because I have no training in coding and I can make some ok stuff. Still it gets so anoying when I don’t know how to do somthing.

I used the WebDev dashcode IDE. The iPhone distribution is nice, but a good web app would target all web-enabled devices. I don’t like the Dashcode interface… yet. iUi is probably a better toolkit for building an interface. Put it on a Rails/Django web app, and you could build an app that runs on any platform.
