Yes, sure - here it is. In two versions - one is the same wxdemo with a
statictext added, the other is still the same but app.MainLoop instead of
the reactor. The second one works, the first does not.

Version 1:

from wxPython.wx import *

from twisted.internet import wxreactor
wxreactor.install()
from twisted.internet import reactor

# set up so that "hello, world" is printed once a second
def helloWorld():
    print "hello, world"
    reactor.callLater(1, helloWorld)
reactor.callLater(1, helloWorld)

def twoSecondsPassed():
    print "two seconds passed"

reactor.callLater(2, twoSecondsPassed)

ID_EXIT  = 101

class MyFrame(wxFrame):
    def __init__(self, parent, ID, title):
        wxFrame.__init__(self, parent, ID, title, wxDefaultPosition,
wxSize(300, 200))
        menu = wxMenu()
        menu.Append(ID_EXIT, "E&xit", "Terminate the program")
        menuBar = wxMenuBar()
        menuBar.Append(menu, "&File");
        self.x=wxStaticText(self,-1,'dupadupa')
        self.SetMenuBar(menuBar)
        EVT_MENU(self, ID_EXIT,  self.DoExit)

    def DoExit(self, event):
        self.Close(true)
        reactor.stop()

class MyApp(wxApp):

    def OnInit(self):
        frame = MyFrame(NULL, -1, "Hello, world")
        frame.Show(true)
        self.SetTopWindow(frame)
        return true

def demo():
    app = MyApp(0)
    reactor.registerWxApp(app)
    reactor.run(0)

if __name__ == '__main__':
    demo()


Version 2:


from wxPython.wx import *

from twisted.internet import wxreactor
wxreactor.install()
from twisted.internet import reactor

# set up so that "hello, world" is printed once a second
def helloWorld():
    print "hello, world"
    #reactor.callLater(1, helloWorld)
#reactor.callLater(1, helloWorld)

def twoSecondsPassed():
    print "two seconds passed"

#reactor.callLater(2, twoSecondsPassed)

ID_EXIT  = 101

class MyFrame(wxFrame):
    def __init__(self, parent, ID, title):
        wxFrame.__init__(self, parent, ID, title, wxDefaultPosition,
wxSize(300, 200))
        menu = wxMenu()
        menu.Append(ID_EXIT, "E&xit", "Terminate the program")
        menuBar = wxMenuBar()
        menuBar.Append(menu, "&File");
        self.x=wxStaticText(self,-1,'dupadupa')
        self.SetMenuBar(menuBar)
        EVT_MENU(self, ID_EXIT,  self.DoExit)

    def DoExit(self, event):
        self.Close(true)
        reactor.stop()

class MyApp(wxApp):

    def OnInit(self):
        frame = MyFrame(NULL, -1, "Hello, world")
        frame.Show(true)
        self.SetTopWindow(frame)
        return true

def demo():
    app = MyApp(0)
    app.MainLoop()
    #reactor.registerWxApp(app)
    #reactor.run(0)

if __name__ == '__main__':
    demo()
