I would suggest to do it using a 3D scene.
http://wiki.freepascal.org/BGRABitmap_tutorial_15
Though not sure about the exact shape in 3D. It is kind of round rectangle that has a certain height, and at the top there is yet another rounding.
Note that you don't need to have a lot of polygons to have a nice rounded phong lighting. See for example in bgrabitmap/test/bgratutorial3d the cylinder (example 3). By setting scene.DefaultLightingNormal to lnVertex you get a rounded effect even with low polygon count.
