What you're trying to do is not a trivial thing to do.
I'd say that the first step would be to create your own cell renderers
for the cells of every row,
then you should expand the height of the cells of the selected row and
draw a window on top of that.

In any case, that is just a hack, TreeView is not the right tool to do
something like this, I'd rather implement a GtkCellLayout from scratch
but that comes with its own set of problems.
