You assign to the same array index three times (label[tt] = /*...*/;
label[tt] = /*...*/; label[tt] = /*...*/)

...and pack the same widget (label[tt]) three times.  GTK widgets can
only have one parent, adding them several times is incorrect.  You need
to pack the first widget before setting the label[tt] to the new one.

Or more likely, you need to remove the loop and use 3 different
variables (or indexes), the loop seems to be misused.  A loop runs the
*same* body several times, it doesn't magically make different
assignations to the same index work like if they were different ones.
