I did it this way:
#####################
from Tkinter import *

listItems = """first second third
               fourth fifth sixth
               seventh eighth ninth
               tenth eleventh twelth""".split()

class App:
   def __init__(self, parent):
      self.lt_lbl = Label(parent, text="Left label")
      self.lt_lbl.grid(row=0, column=0)
      self.lt_add_btn = Button(parent, text="Left add button")
      self.lt_add_btn.grid(row=0, column=1)
      self.lt_rem_btn = Button(parent, text="Left remove button")
      self.lt_rem_btn.grid(row=0, column=2)

      scrollList = Frame(parent)
      self.lt_lstbx = Listbox(scrollList)
      self.lt_lstbx.pack(side=LEFT)
      self.lt_scrlbr = Scrollbar(scrollList)
      self.lt_scrlbr.pack(side=RIGHT, fill="y" )
      scrollList.grid(row=1, column=0)

      for item in listItems:
         self.lt_lstbx.insert(END,item)

tk = Tk()
app = App(tk)
tk.mainloop()

Note that I created a frame to hold both list box and scrollbar and 
used
the packer to put them together.

However I would personally use the packer rather than the grid for the
whole GUI.
I'd create a frame for your buttons and label and pack them with
the label on the left and buttons on the right, then another frame
for the scrolled list as above then simply pack the two frames into
the root window.

YMMV,
