Okay... I have an idea for how this could be done.

I confess I'm biased against it, due to the difficulties and
inefficiencies it raises in the implementation.

How's this (syntax as of tonight - I'll upload it tomorrow):

window w("Test Window");
grid g(2, 2);
g.contain(button("Click me", on_click), 1, 1);
g.contain(label("Enter your name:"), 0, 0);
textentry t();
g.contain(t, 1, 0);
wait_for_signal(w.delete_signal()); // note () after delete_signal
