Chances are you are going to want to store some type of image in those pixbuf(s). You are placing the number of elements in the wrong place.

To declare the array, use:

Glib::RefPtr<Gdk::Pixbuf> framebuffer[numFrames];

Then to create the Pixbuf, you can use one of the following:

framebuffer[somenumber] = Gdk::Pixbuf::create_from_file("...");
framebuffer[somenumber] = Gtk::Invisible::render_icon(...);

There are plenty of other functions at http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGdk_1_1Pixbuf.html

There are also a few constructors listed which I believe you could just use this, although I'm not quite sure if you need Glib::RefPtr before the constructor or even if this example would work:
framebuffer[somenumber] = new Gdk::Pixbuf(...);

I hope this helps...
