           font = wxFont(12, wxMODERN, wxNORMAL, wxNORMAL)
           dc.SetFont(font)

Notice that the font size is 12 (although this is rather arbitrary).  If you
want a different font size, you'll also want to change the line spacing in
MyPanel.draw().  This being the case, I would recommend using an attribute to
MyPanel to keep track of the font size and adjusting the line spacing
accordingly:

class MyPanel(wxPanel):
    def __init__(self, parent, fontsize = 12):
        wxPanel.__init__(self, parent, -1)
        self.SetBackgroundColour(wxWHITE)
        self.text = []
        self.fontsize = fontsize
        EVT_PAINT(self, self.OnPaint)

    def draw(self, dc):
        dc.Clear()
        font = wxFont(self.fontsize, wxMODERN, wxNORMAL, wxNORMAL)
        dc.SetFont(font)
        y = 0
        for t in self.text:
            dc.DrawText(t, 0, y)
            y += self.fontsize + 2
