How to use the gooey.gui.util.wx_util.h1 function in Gooey

def _do_layout(self):
    self.SetDoubleBuffered(True)

    container = wx.BoxSizer(wx.VERTICAL)

    container.AddSpacer(20)
    self.SetSizer(container)
    thing.SetSelection(0)

    self.Bind(wx.EVT_LISTBOX, self.onClick, thing)

def layoutComponent(self):

        self.SetBackgroundColour(self.buildSpec['header_bg_color'])
        self.SetSize((30, self.buildSpec['header_height']))
        self.SetMinSize((120, self.buildSpec['header_height']))

        self._header = wx_util.h1(self, label=self.buildSpec['program_name'])
        self._subheader = wx.StaticText(self, label=self.buildSpec['program_description'])

        images = self.buildSpec['images']
        targetHeight = self.buildSpec['header_height'] - 10
        self.settings_img = self._load_image(images['configIcon'], targetHeight)
        self.running_img = self._load_image(images['runningIcon'], targetHeight)
        self.check_mark = self._load_image(images['successIcon'], targetHeight)
        self.error_symbol = self._load_image(images['errorIcon'], targetHeight)

        self.images = [
            self.settings_img,
            self.running_img,
            self.check_mark,
            self.error_symbol
        ]

Note! Mutates `self.reifiedWidgets` in place with the widgets as they're
        instantiated! I cannot figure out how to split out the creation of the
        widgets from their styling without WxPython violently exploding
