Oh... yeah, sorry about that. The GTK tutorial is way out of date.
It's been on my TODO list for ages, but that doesn't really help much.

Here's a GTK2 hello-world:

int main()
{
    GTK2.setup_gtk();
    GTK2.MessageDialog(0, 0, GTK2.BUTTONS_OK, "Hello, world!")->show();
    return -1;
}

Yes, it's not as short as the GTK.Alert form, but MessageDialog does a
lot more. If you want more of a language-level Hello World, try this:

int main()
{
    write("Hello, world!\n");
}

Check out my GitHub repositories for some cool stuff you can do with Pike.

I use it for back-end work (although you won't see all of that there,
as my biggest projects aren't public), GUI applications (Gypsum,
StilleBot, Zawinski), data processing scripts, file management tools,
and all manner of one-shot scripts. Pike stands alongside Python in my
toolbox of easy and convenient languages.

If you want to get into GTK work, definitely use GTK2 (Pike doesn't
have GTK3 bindings as yet, and GTK1 isn't worth hanging onto), but on
Windows, that means you have to choose between the latest Pike with a
slightly older GTK, and the latest GTK on a slightly older Pike. I
recommend the former, until such time as you run into a problem.

Have fun learning Pike! It's a great language.
