Compile and Run Qt programs in ubuntu 12.04

[stbb24]

How can I compile and run Qt programs in ubuntu 12.04??I tried using

g++ sample.cpp -o sample
sample.cpp:1:22: fatal error: qt4/QtGui: No such file or directory

g++ sample.cpp -o sample
sample.cpp:1:22: fatal error: qt4/QtGui: No such file or directory

To copy to clipboard, switch view to plain text mode 

but it gives an error

and I double check the installation files of Qt and everything is there

Any comments???

First see the documentation page, you need to run qmake -project first to generate project, then run qmake to generate makefile and then run make to build.

Anyway your current problem might be some issue with the path to Qt headers, but first try as described in the getting started page.
