I too fell victim to this when I was installing my test application but 
here's what I found so I hope it helps.

Examine the .exe with dependencywalker to see what dlls it needs, and 
copy these in to the working folder of the installation target.

Take these files from the qt\sdk\qt\bin dir.

If you are using a database like me you also need to copy the 
appropriate database driver into the same folder from your 
plugins\sqldrivers directory.

As regards the icon, create a resource file and add the icons to the 
resource. Set the icon at start up using QIcon(...) in my case:

ui->dbState->setIcon(QIcon(":/form/icons/online")) ;

This way you can use an applicable icon to indicate the databases' state.

Remember to rebuild and copy your application having added the icons and 
all should be well.
