GADGETCLASS should be "frbuttongclass", e.g.:
gad = (struct Gadget *) NewObject(NULL, **"frbuttongclass"*,*
GA_Left, win->BorderLeft + 5,
GA_Top, win->BorderTop + 5,
GA_Width, 64,
GA_Height, 64,
GA_Border, &border,
GA_Highlight, GFLG_GADGHCOMP,
GA_Immediate, TRUE,
GA_RelVerify, TRUE,
TAG_DONE);
Simple mistake :)
