I need a widget with vertical tabs/buttons with text, as in JEdit. You
can get an idea from the left part of the image here:

How do I do this in GTK+ ?

Basically, you can't currently.

Is this planned for future versions of GTK+ (say 2.4) ? It seems this
can be done in QT
( , Swing
(previous figure), Windows (used by Topstyle,, etc.), etc.

It's been on the TODO list for a while... probably not 2.4 at this
point, but likely by 2.6.

A possible workaround:

 - Draw the text to a pixmap (using gdk_draw_pango_layout())
 - Retrieve that back into a GdkPixbuf (gdk_pixbuf_from_drawable())
 - Put the GdkPixbuf into the button (Add a GtkImage to an
   empty GtkButton)

Seems rather complicated :-( Where do I rotate the text ? Do I rorate
the pixbuf after rendering the text or something ?

You'll have to write your own rotation function (using the ability
to access the pixel data for GdkPixbuf) or find one somewhere ...
GTK+ doesn't have a rotate function built oin.

But the idea of getting it to a pixbuf is that it is possible to
write such a function since access to the pixel data pretty easy.
