Native Development, Is it possible to compile apps for opie? Options

[YoG]

Hi,
I've seen hrw's message that native development should work.
So I went and installed:
gcc
binutils
and libc6-dev.
and compiled helloWorld.c with out a problem (and it even runs!)

CODE

#include <stdio.h>

int main(void)
{
    printf("Hello World!\n");
    return 0;
}

Now I wish to compile some apps for opie (with gui and everything...) the question is:
is it possible?
and if it is:
how?

Thanx,
YoG.
