Well, yes, if you have a virtual machine that works on your platform, then
Java will work. ;-) Most likely AWT's peer classes are implemented with
Carbon code. (Wouldn't it make more sense to do this with Cocoa? I guess
it's less work. But Cocoa is supposed to be good for RAD, right?) Swing is
lightweight, so it doesn't require any native code (it's implemented in
Java). I don't know if any other packages have peer classes.

<sorta rant>
I'm really not sure why Sun doesn't have more heavyweight stuff, as it
should be faster (maybe it's not?). I can understand the desire to avoid
native code, but why not write them in Java, then convert them to native
code (or compile them into native binaries as opposed to bytecode). If you
could compile them once and cache the resulting code somewhere, that could
significantly speed up Java. (I don't mean avoid bytecode, I mean write
Java, compile it into bytecode, and distribute it. Then when the user runs
it, any code they run is compiled via a JIT compiler (libraries could be
compile with a "real" compiler), and is cached somewhere. When they want
to run it again, it's already compiled so they avoid interpreting it.
