The challenge to create iPhone apps

Has anyone developed iPhone apps? As soon as I came back to Japan in April, I bought the iPhone. and I've always dreamt of making iPhone apps myself. Now that I have a littile time lately, I decided to start developing the iPhone apps from scratch. Honestly, I have no programing experience so far, so I'm sure it's going to be quite hard! But the iPhone also seems an opportunity for people like me who had no idea about it, because lots of iPhone apps are not produced by professional developers! In fact , a lot of newcomers have been taking part in apparently. I believe the iPhone has such an attraction.

Anyway, I"d like to make my goals which I want to accomplish by the end of this year. Here are the ones.

To launch at least one app on "App Store".
To make the promotion Web site of the app.

I've got to learn a lot, because I don't know anything now. but it must be going to be a fun! I'll do my best^^
