I could use some help with making a GUI in Unity!

I need help with how I would go about making a GUI like the image. 1 - would be the main game window where I will be adding a platformer RPG, while 2-7 would all be a GUI that is constantly open. Does anyone have advice or can point me in the proper direction of how to implement something like this?

  1. Select your camera and set the Viewport Rect values to X = 0, Y = 0.2, W = 0.6, H = 0.8 (change the values according to your needs)
  2. Create a Canvas
  3. Create two empty, children of your canvas
  4. Set the anchors of the 1st one to Xmin = 0, Ymin = 0, Xmax = 0.6, Ymax = 0.2 => You get your panel containing #7
  5. Set the anchors of the 2nd one to Xmin = 0.6, Ymin = 0, Xmax = 1, Ymax = 1=> You get the panel containing #2, #3, #4, #5 & #6
