hi bro its so easy
u first in secDialog create a slot/method for examle:

clsass secDialog:..
{
...
public:
 void setBtn(QString btnName,bool vis){
//... write a sloution to show or hide a button with btnName and vis
}

so u create a object from seDalog in MainWindow and call method :

mainwindow()//constructor
{
 * dlg=new secDialog();
}

void btnClicked(){
dlg->setBtn("btnxxx",false);
}
}

good luck
