* for cursor position, get an iter :

 $iter = $this->buffer->get_iter_at_mark($this->buffer->get_mark('insert'));

(here buffer is a GtkTextBuffer or GtkTextView::get_buffer())

* moving cursor should be a forward, backward method in Textview, but
can't see anyone. Perhaps you could move a special mark named
'insert'.

* you don't need to move cursor to select some arbitrary text in
TextBuffer. So perhaps you don't need to move cursor.

* text modification in usualy made with (beetween) 2 GtkTextIter :
 - iters can be returned from selection,
 - can be computed depending on application context.
 - some method are available for this.

after that, have a look in GtktextBuffer : delete, insert ...

-have a look a kksou site for some examples.
- I have uploaded a simple example with GtkTextedit here with a screen
shot. Don't know exactly what it contains ands perhaps some
optimisations may be needed.

Now I al working on a Wysiwyg editor with GtkTextView. Actual source
code is also available at the same location.
