I can help you with the text color. I am using QT with Python, you didn't mention what language you are using.

In my application I create a Close button that has the "Close" text colored red. Here is the code:

quit = QtGui.QPushButton('Close', self)
quit.setStyleSheet("QPushButton { color: rgb(255,50,50); }")

The first line creates the QPushButton, and the second sets the color through the "setStyleSheet()" method. This works good for me. You can also modify other settings as well.

--EDIT-->

I believe that you could do the same thing in C++ with (assuming that qQuit is the pointer to my "Close" QPushButton):

qQuit->setStyleSheet("QPushButton { color: red }");
