You have two options:
* In glade insert one-element, empty hbox (or vbox) instead of
combobox, and then in runtime create a box with comboBoxNewText and
add it into the hbox (or vbox). Now you can use comboBoxAppendText.
* In glade insert comboBox as you do it now and in runtime add a model
to that box (see attribute comboBoxModel). I am, however, not well
versed in haskell interface to gtk+ so I can't help you with a model
part (you can see how it is done for TreeView widget though).

Thanks Piotr for reply so faster. I have tried to do the two options
(firstly the second, which I have not do anything good because the
models' dificulty). Then the first, I tried and I can do almost I
want, but I can not connect the hvox with the comboBoxNewText even I
read the Duncan's answer. Thanks you two very much.
