Yes. Use gzillabytesink, gzillaimgsink, gzillaimage, and gzillajpeg from the 
latest gzilla release (available at www.gzilla.com). You'll also need the 
IJG jpeg library (the same one that the GIMP uses). The invocation looks 
something like this:

GzillaByteSink *bytesink;
GzillaImgSink *imgsink;

imgsink = gzilla_image_new (width, height, "", bg_color);
bytesink = gzilla_jpeg_new (imgsink);

/* Pack bytesink->widget into the container of your choice here. */

gzilla_bytesink_write (bytesink, buf, bufsize);
...

gzilla_bytesink_close (bytesink);

For large images, try to split up the bytesink_write calls into multiple 
iterations of the idle loop - this will prevent the UI from stalling 
while the image is being decoded - a fairly CPU intensive process.

Good luck!
