cannot get makefile to work with Qt library

Question

I have 3 files in my program: App_interface.h, App_interface.cpp, main.cpp. Im trying to compile my program which requires the Qt library. I just installed the Qt library in the default location. This is my makefile:

if your wondering why i don't use moc in this makefile is because 1) i dont know how to do that. 2) i just want to stop getting the compiler error "cannot find ... file".

thanks

# Project: App_interface
# 10-19-09
# 

# general variables
CPP := g++
OBJS := main.o App_interface.o

# Qt directorys
QTLIB := /usr/local/Trolltech/Qt-4.5.3/lib

QTINC := /usr/local/Trolltech/Qt-4.5.3/include
QTMOC := /usr/local/Trolltech/Qt-4.5.3/bin

App_interfaceV1: $(OBJS)
    $(CPP) $(OBJS) -o App_interfaceV1 $(QTLIB) 

main.o: main.cpp App_interface.h 
    $(CPP) -B $(QTINC) -c main.cpp -o main.o 

App_interface.o: App_interface.h
    $(CPP) -B $(QTINC) -c App_interface.cpp -o App_interface.o

There are several problems: You should use -I $(QTINC) to compile files, -L $(QTLIB) and at least -lQtCore -lQtGui to link the application. To get more help you should provide exact error messages.

Sorry to be blunt, but if you don't know how to write Makefiles, I'd suggest to use qmake.
