files is a QStringList. Your code should be something like this:

for file_ in files:
  data = ""
  f = open(file_)
  data = file.read()
  self.listWidget.addItem(file_)

Alternatively you may use "self.listWidget.addItems(files)" to add them all in 
one go. Please read the Qt documentation. It will give you details about the 
API. A good tutorial like the one written by Roberto Alsina (s. this list for 
details) would help as well.

That is just an example for the dialog's title.
