How can I write a form from scratch, without using awt, swing or lwuit?
You tell us what you don't want to use, but give us no clue as to what you do want to use or your reasons for not using the others. Also you may want to tell us more on just what you mean by a "form".Quote:

Why in the world would you not use Swing/AWT?
By form I mean a GUI form. The reason why I want to build it from scratch is I’m tired of fumbling in the dark every time I want to do something which leans half an inch outside the box. So let’s pretend swing and awt do not exist and I want to create a form, how do I do it?
You have to draw each and every pixel yourself; and that is just for the view part. You also have to implement the entire feel part for each component. Better use Swing.Quote:

Sounds like Java is not the language for you. Java deliberately restricts you to doing things in portable ways.Quote:

So yeah... you want to code forms "outside the box", find a Java binding to your platform's native window/widget library (like this) or write your own.
Ok, I'll let it go. But for the record, I don't think "accurate dragging on a touch screen", to give you an example, is possible using either swing, awt or (in the case of midlets) lwuit. The fact that they average the width of the touched surface means that any slight difference of pressure or rolling of the finger will translate into a movement.
I don't think the type and precision of the pointer input device are even accessible to the standard Java API. Java operates at a much higher level of abstraction. The details of pointer hardware probably demand native code and JNI bindings.
