I'd just put three sliders into a vbox.

Do it model-view-style to avoid feedback. So you have a data structure
with three ints for start/middle/end and methods called set_start(),
set_middle() and set_end() that change the values and enforce your
constraints (start < middle < end I guess).

Each method finishes by signalling to the three sliders to update
themselves, each slider responds to it's own "value_changed" signal by
calling the appropriate method, and responds to "changed" from the
model (your three ints) by updating itself and blocking it's own
"value_changed" signal for that update only.
