python qt4不规则图形界面如何添加按钮呢？

Question

from PyQt4.QtGui import *
from PyQt4.QtCore import *

class MyForm(QWidget):
    def __init__(self,parent=None):
        super(MyForm,self).__init__(parent)

        self.pix = QPixmap("1.png")
        self.resize(self.pix.size())
        self.setMask(self.pix.mask())
       
    def paintEvent(self,event):
        painter = QPainter(self)
        painter.drawPixmap(0,0,self.pix.width(),self.pix.height(),self.pix)
       

app = QApplication([])
form = MyForm()
form.show()
app.exec_()

比如此代码：如何添加一个pushButton和事件呢？

不用控件。要自己画吧。。 我猜的。。
