Maziar,

first you should get an idea what you really want to do, how complex your menues will be and how many of them you need (you can build every menue "by hand" or use some complex routines for this).

Once I wrote LCD code to run a 240*128 pixel graphic LCD with a touchscreen key matrix on its surface. The code was not that simple because I needed routines to draw a menue with text and buttons (assigned to several matrix points and the desired action). The easier you want it building the menue tree, the harder you got it writing the comfortabe-to-use menue routines.

If you want to have a look at my old LCD library drop me a line and I'll email it to you. But the source is in assembler and the comments are in german! 8)
