GTK+ is a comprehensive GUI toolkit that provides a rich set of widgets and a native look and feel across platforms, making it suitable for general application development. wxSVG, on the other hand, is specialized for SVG graphics, offering lightweight and efficient rendering, but is less versatile for broader application needs.
