In D it's very simple to embed resources in the executable at compile 
time using string imports:

immutable data = cast(immutable(uyte[]) import("foo.ico");

Compile by adding the -J flag to point to the directory where the icon 
files are located:

dmd main.d -J./resources

Then I'm pretty sure there's a an API that takes a byte array and 
returns an image of some sort.
