[java] is it possible to pixel plot with java at good fps

say i wanted to make my own polygon rendering engien in java. is it possible to get high fps and plot pixels. useing java alone. say at least 50 to 60 fps. i have attempted this in fullscreen however max fps i can achieve is near 33. without rendering anything but the background. is it a must to use something like lwjgl or is thier another way. light~~~~~~~~
