[Interest] Preferred way to create custom look-and-feel GUI

[Jérôme Godbout]

If you are not into an hurry, I would go Qt 5.6 and make sure you get the
new way to put style on Items in mind:Qt Quick Controls 2
http://blog.qt.io/blog/2015/11/23/qt-quick-controls-re-engineered-status-update/

It should be part of Qt 5.7
So if you're not into an hurry and can work on the rest of the thing of
your application, I would go Qml, keep the Controls component wrap into
custom Component, you will later skin it into that component, should be
fast and easy if you have it into mind.

You can also use a singleton (optionally with a loader to load current
theme) to keep many of the properties like color, dimension, scale, etc...
