Developing mobile applications

[Mise]

I want to make an application for my mobile phone that shows the London Underground map, travel times between stations, quickest route from A to B, maybe some other stuff...

I know in my head how this will look, and I'm confident that I can actually program it (it's fairly simple), but I have no idea how to develop a program for a mobile phone. I just don't know where to start.

I was hoping one of you guys had some experience in this, and could point me in the right direction, to resources and whatnot on the internet. How long would it take me to make a Hello World application?

What phone do you have? Each OS is different to program.

you could use Java, J2ME to be precise

with "J2ME" as keyword you should be able to get a few tutorials...I've never actually used J2ME myself, but it can't be that hard if you understand Java.

Thanks, I shall look this up. My phone can play Java games, so I guess this is where I should start!
