Welcome to the forum and Qt.
You should really start by reading the docs (http://doc.trolltech.com/4.3/), since they are very good, and most of your questions here are answered in the docs.

lease give me example wi program using QT4.3 designer
From Qt4, designer is only a UI design tool, you do not program with it.
About using designer, read the this (http://doc.trolltech.com/4.3/designer-manual.html).

with compiling steps
Do you mean general compiling C++, or Qt specific?
If you mean C++, then I would suggest that you let go of Qt for now, and learn C++ first.
If its Qt you mean, read this (http://doc.trolltech.com/4.3/qmake-manual.html).

and also how to use signals and slot in Qt4.3,
Here (http://doc.trolltech.com/4.3/signalsandslots.html) you go.

should we must creat *.cpp and *.h file be created manually?,
What do you mean by that?
You have to code... Qt is a UI library, not a "autogen" tool....

Also, we have a very nice wiki, (http://wiki.qtcentre.org/index.php?title=Main_Page) have a look there too.
