Well, since no one has suggested anything, make your own
widget.

In theory one can look at GtkProgressBar code and make
a widget that looks similarly, except for the colouring and
multiple bars.  In practice the progress bars are painted
with gtk_paint_box() which uses the Gtk style, and even if
one hackisly modified it on the fly or supplied another
style, a theme engine could still draw things its way
ignoring your colors.

So I would just take a drawing area (or subclass GtkWidget)
and draw some colorful rectangles on it, possibly with
borders or text or anything.  That's easy with gdk_draw_*()
functions whereas emulating GtkProgressBar look is not and
I would not attempt that.

It's the old struggle between the app and the theme again...
