I've installed Qt 5.1.1 in Windows 7 (mingw 4.8 + openGL). However, I can't get the simple 'hello word' (from version 4) to compile and run. Is there are simple guide to running simple programs, so that I can get started? I've looked through all the installation and tutorial documentation, which mostly tells me about things I don't need to know. I only want to develop a simple GUI - it should be easy with Qt but it seems far from clear.

There is a subtle difference in the .pro file. For version 5 you need to add
QT += widgets
Respectively in order to remain compatible with Qt4 you can add in the .pro file:
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
Other than that you need to post the error return you receive.
Hi and welcome to devnet,
Since you took a Qt 4 widget example you are probably missing
@QT += widgets@
In your pro file. You can start using a new widget project from Qt Creator and it will be setup for you.
