You'd need to know the location of this "wx" module. There could be a directory containing the file __init__.py
Or there might be a file called wx.py
Or some other possibilities.

If P is the path to that directory's parent,

import sys
sys.path.append(P)

where P is a string.
If you're on a windows system the latter statement will probably look like

sys.path.append(r'c:\some\path')

If on a unix like system without weird characters in the path the latter statement will look more like

sys.path.append('/usr/local/python3.2/lib/some/path')

Or on unix

Code:

$ PYTHONPATH=/some/path:$PYTHONPATH python3

and you could put PYTHONPATH into your shell startup script.

wxpython is some sort of GUI builder?

I encourage you to learn how to use python---how to use the various data container objects and their purpose, and get a feel for the syntax before continuing with a major project.

What version of Python are you using?

For Python27 you can download the Window installer
http://downloads.sourceforge.net/wxpython/wxPython2.8-win32-unicode-2.8.12.1-py27.exe

Run the .exe file and it will install the wx package for instance into folder

C:\Python27\Lib\site-packages\wx-2.9.1-msw\wx

Python will find folder wx now.

Alright! Now you can test this code ...

Code:

import wx
import wx.lib.filebrowsebutton

class MyFrame(wx.Frame):
    def __init__(self, parent, mytitle, mysize):
        wx.Frame.__init__(self, parent, wx.ID_ANY, mytitle, 
            size=mysize)
        self.SetBackgroundColour("green")
        panel = wx.Panel(self)

        # this file browser masked to look for .wav sound files 
        self.fbb = wx.lib.filebrowsebutton.FileBrowseButton(panel,
            labelText="Select a WAVE file:", fileMask="*.wav")
        play_button = wx.Button(panel, wx.ID_ANY, ">>  Play")
        self.Bind(wx.EVT_BUTTON, self.onPlay, play_button)

        # setup the layout with sizers
        hsizer = wx.BoxSizer(wx.HORIZONTAL)
        hsizer.Add(self.fbb, 1, wx.ALIGN_CENTER_VERTICAL)
        hsizer.Add(play_button, 0, wx.ALIGN_CENTER_VERTICAL)
        
        # create a border space
        border = wx.BoxSizer(wx.VERTICAL)
        border.Add(hsizer, 0, wx.EXPAND|wx.ALL, 10)
        panel.SetSizer(border)

    def onPlay(self, evt):
        filename = self.fbb.GetValue()
        self.sound = wx.Sound(filename)
        # error handling ...
        if self.sound.IsOk():
            self.sound.Play(wx.SOUND_ASYNC)
        else:
            wx.MessageBox("Missing or invalid sound file", "Error")


app = wx.App()
# create a MyFrame instance and show the frame
mytitle = "wx.lib.filebrowsebutton.FileBrowseButton and wx.Sound"
width = 600
height = 90
MyFrame(None, mytitle, (width, height)).Show()
app.MainLoop()
