Hii

I am very new to Nokia development and have spent days looking for answer in code examples.

This might seem very silly but I am sure people in this community will help me out.

I am trying to develop an app for Asha s40 platform

it is supposed to have a drop down menu and an image grid.

and images in grid change when user clicks on them.

sounds simple

but I have searched a lot and all I get is sample screens and no code examples

please help me out .. wht should I use lcdui or eSWT or lwuit???
