[news.eclipse.platform.swt] GEF and SWT standalone application

Here is the code of my window :

protected Control createContents(Composite parent)
{
	//The whole window (I suppose so)
	Composite composite = new Composite(parent, SWT.BORDER);
	composite.setLayout(new FillLayout());

....

//The graphical editing zone

Composite arbre = new Composite(composite, SWT.BORDER);
viewer = new ScrollingGraphicalViewer();
viewer.setEditDomain(editDomain);
viewer.createControl(arbre);
arbre.setLayout(new FillLayout());

...

FormData formArbre= new FormData();
formArbre.top = new FormAttachment(0,10);
formArbre.left = new FormAttachment(0,10);
formArbre.right = new FormAttachment(100,-10);
formArbre.bottom = new FormAttachment(50,-10);
arbre.setLayoutData(formArbre);


...


//The tabfolder zone

TabFolder tabFolder = new TabFolder(composite,SWT.NONE);
tabFolder.setLayout(new FillLayout(SWT.VERTICAL));

...


FormData formongl = new FormData();
formongl.top = new FormAttachment(arbre,10);
formongl.left = new FormAttachment(0,10);
formongl.right = new FormAttachment(30,-10);
formongl.bottom = new FormAttachment(100,-10 );
tabFolder.setLayoutData(formongl);

...

//The tabletree zone


Composite fillComp1 = new Composite(composite, SWT.BORDER);
fillComp1.setLayout(new FillLayout(SWT.HORIZONTAL));

...

FormData formComp = new FormData();
formComp.top = new FormAttachment(arbre,10);
formComp.left = new FormAttachment(tabFolder,10);
formComp.right = new FormAttachment(60,-10);
formComp.bottom = new FormAttachment(100,-10 );
fillComp1.setLayoutData(formComp);

...

// Button

Composite fillbutt = new Composite(composite, SWT.BORDER);
RowLayout rl = new RowLayout(SWT.VERTICAL);

...

FormData formButt = new FormData();
formButt.top = new FormAttachment(arbre,10);
formButt.left = new FormAttachment(fillComp1,10);
formButt.right = new FormAttachment(70,-10);
formButt.bottom = new FormAttachment(100,-10 );
fillbutt.setLayoutData(formButt);

...

//The final zone

Composite fillComp2 = new Composite(composite, SWT.BORDER);
fillComp2.setLayout(new FillLayout(SWT.VERTICAL));

...

ormData formComp2 = new FormData();
formComp2.top = new FormAttachment(arbre,10);
formComp2.left = new FormAttachment(fillbutt,10);
formComp2.right = new FormAttachment(100,-10);
formComp2.bottom = new FormAttachment(100,-10 );
fillComp2.setLayoutData(formComp2);

  I had this when my graphical zone was a simple canvas using Draw 2D

zone, so my window is a JFace Application Window.
so do I have to reimplement all the others elements with GEF and MVC ?
I asked this in eclipse.tools.gef, and I was answererd that I could 
resolve this problem with only SWT (and/or Jface) , without using more MVC .

Thanks
