In the documentation [1] it says:

    GtkText is deprecated and unsupported. It is known to be buggy. To use
it, you must
    define the symbol GTK_ENABLE_BROKEN prior to including the GTK+ header
files.
    Use GtkTextView instead.

That might be the reason it doesn't show up in Vala, although I'm not sure
myself.
