Used QGesture for this as per the gesture example. Moved the help and info text to separate lines. Enabled word wrap to prevent text going off screen. As a drive-by, the code to center the window at a size that's a fraction of the screen is replaced with a simple sizeHint() override. The user should have control over placement, particularly now that it should be placed manually onto a touchscreen if the user has one.
