You cannot drop it to a form, but you can have a toolbar activated in a top level form.
ShowWindow property of your toolbar class must be "In Top Level form"
Check this code:

PUBLIC oForm
oForm = CREATEOBJECT('form1')
oForm.visible = .t.


**************************
DEFINE CLASS form1 AS form
	Height = 333
	Width = 480
	ShowWindow = 2

	AutoCenter = .T.
	Caption = "Form1"
	toolbarref = .NULL.
	Name = "Form1"

	ADD OBJECT command1 AS commandbutton WITH ;
		Top = 200, ;
		Left = 290, ;
		Height = 27, ;
		Width = 84, ;

	ADD OBJECT command2 AS commandbutton WITH ;
		Top = 200, ;
