Design/Layout question (PySide)

[simchris111]

Hey guys, I've been playing around with PySide for a while now, it rocks my socks off! I started with the designer, but I actually found it hard to achieve specific layouts. So after googling, I found that some guys recommended doing it with code instead, which is what I'm doing now.

However, I really struggle to achieve the specific layout I want, I've attached a couple of images. The original (the one I have now) first: "Link <original window>":http://s27.postimg.org/4vu8kheab/app_original.jpg

And this is what I want:
!http://s28.postimg.org/hc4s7b8xp/app_new.jpg(What I want)!

I would appreciate it if anyone could point me in the right direction here, and if the way I've written the code is wrong/messy or anything, please tell me :)

Here's the code I have so far:
@import sys
from PySide import QtCore, QtGui

class Window(QtGui.QWidget):
def init(self, parent=None):
super(Window, self).init(parent)
#Create the layouts
layout_main = QtGui.QVBoxLayout()
layout_left = QtGui.QVBoxLayout()
layout_right = QtGui.QVBoxLayout()
layout_bottom = QtGui.QHBoxLayout()
#Create the frames
frame_main = QtGui.QFrame()
frame_left = QtGui.QFrame()
frame_right = QtGui.QFrame()
#Set options for the layouts
layout_left.setAlignment(QtCore.Qt.AlignTop)
layout_right.setAlignment(QtCore.Qt.AlignTop)
#Set options for the frames
frame_left.setMinimumWidth(300)
frame_left.setFrameShape(QtGui.QFrame.StyledPanel)
frame_right.setMinimumWidth(300)
frame_right.setFrameShape(QtGui.QFrame.StyledPanel)
#Set the style to Cleanlooks
QtGui.QApplication.setStyle(QtGui.QStyleFactory.create('Plastique'))

    #Add widgets to the left and right layout
    widget_cal1 = QtGui.QCalendarWidget(self)
    widget_cal2 = QtGui.QCalendarWidget(self)
    widget_cal1.setFixedHeight(220)
    widget_cal2.setFixedHeight(220)
    btn_1 = QtGui.QPushButton('Button 1')
    btn_2 = QtGui.QPushButton('Button 2')
    layout_left.addWidget(widget_cal1)
    layout_right.addWidget(widget_cal2)
    layout_left.addWidget(btn_1)
    layout_right.addWidget(btn_2)

    #Add lower buttons
    btn_x = QtGui.QPushButton('Button X')
    btn_y = QtGui.QPushButton('Button Y')
    layout_bottom.addWidget(btn_x)
    layout_bottom.addWidget(btn_y)
    #Add the buttons to the left layout
    layout_left.addLayout(layout_bottom)

    #Create a QSplitter widget and add the left and right frames into it
    splitter = QtGui.QSplitter(QtCore.Qt.Horizontal)
    splitter.addWidget(frame_right)
    splitter.addWidget(frame_left)
    #Set the QSplitter to not bein collapsable
    splitter.setCollapsible(0, False)
    splitter.setCollapsible(1, False)
    #Add the splitter to the mainLayout
    layout_main.addWidget(splitter)

    #Set the layout for the frames
    frame_main.setLayout(layout_main)
    frame_left.setLayout(layout_left)
    frame_right.setLayout(layout_right)

    self.setLayout(layout_main)

    self.setWindowTitle("Split Layout")
    self.resize(920, 420)

#Open the window
if name == 'main':
app = QtGui.QApplication(sys.argv)
w = Window()
w.show()
sys.exit(app.exec_())@
