I now have:

class MyFitButton : public TGTextButton { private:
  TGraph *fGraph;
  TF1 *fF1;

public:
  MyFitButton(const TGWindow *p, TGHotString *s)     : TGTextButton (p, s )
    , fGraph(0), fF1(0) {}

  void SetGraph(TGraph *g) { fGraph = g;}   void SetFun1(TF1 *f) { fF1 = f;}

  TGraph *Graph() const {return fGraph;}   TF1 *Fun1() const { return fF1;}

  ClassDef(MyFitButton,1);
};

.x RogersGUI.C++

segfaults if the following line is uncommented:

fFitButton = new MyFitButton(fHframe2, (TGHotString*)"&Fit");
