Use Grid to approximate what you want. If you want it closer, you can build it up in a Grid with individual uses of Control rather than using Manipulate.

f[x_] = (x + 2) (x - 2);

Grid[{{Manipulate[
     Plot[f[x], {x, -5, 5},
      PlotRange -> {-25, 50},
      Epilog -> {Red, Line[{{x0, -25}, {x0, 50}}],
        Line[{{-5, y0}, {5, y0}}]}],
     {{x0, 0, "x"}, -5, 5, .1,
      Appearance -> "Labeled"},
     {{y0, 0, "y"}, -25, 50, 1,
      Appearance -> "Labeled",
      ControlType -> VerticalSlider},
     ControlPlacement -> {Bottom, Left},
     Paneled -> False],
    Manipulate[
     Plot[f[x], {x, -5, 5},
      PlotRange -> {-25, 50},
      Epilog -> {Red, Line[{{x0, -25}, {x0, 50}}],
        Line[{{-5, y0}, {5, y0}}]}],
     {{x0, 0, "x"}, -5, 5, .1,
      Appearance -> "Labeled"},
     {{y0, 0, "y"}, -25, 50, 1,
      Appearance -> "Labeled",
      ControlType -> VerticalSlider},
     ControlPlacement -> {Bottom, Left},
     Paneled -> False]},
   {Manipulate[
     Plot[f[x], {x, -5, 5},
      PlotRange -> {-25, 50},
      Epilog -> {Red, Line[{{x0, -25}, {x0, 50}}],
        Line[{{-5, y0}, {5, y0}}]}],
     {{x0, 0, "x"}, -5, 5, .1,
      Appearance -> "Labeled"},
     {{y0, 0, "y"}, -25, 50, 1,
      Appearance -> "Labeled",
      ControlType -> VerticalSlider},
     ControlPlacement -> {Bottom, Left},
     Paneled -> False],
    Manipulate[
     Plot[f[x], {x, -5, 5},
      PlotRange -> {-25, 50},
      Epilog -> {Red, Line[{{x0, -25}, {x0, 50}}],
        Line[{{-5, y0}, {5, y0}}]}],
     {{x0, 0, "x"}, -5, 5, .1,
      Appearance -> "Labeled"},
     {{y0, 0, "y"}, -25, 50, 1,
      Appearance -> "Labeled",
      ControlType -> VerticalSlider},
     ControlPlacement -> {Bottom, Left},
     Paneled -> False]}}] // Panel

Thanks Bob, Yes, one can do that, I know, but that is not what I meant.

As I said, when having one plot, i.e. one object, as in your example, then 
it is not much of an issue.

But if one has more than one object being displayed, and some controls are 
meant to affect one object and others to affect another, then it would be 
better to be able to locate the controls next to the object.

Here is a diagram I just made to help explain what I meant.
