The point of using append mode is that you can close the file
and then re-open it.

self.logfile.write('%s,'%( strftime("%Y-%m-%d %H:%M:%S", localtime())))

Although, I would be tempted to just use the csv module (untested
in append mode) and list context.
#import csv (at the top of the module)
with open( filename, 'ab' ) as f: # open as binary to avoid blank rows
writer = csv.writer(f)
data = [ str(field_values.get(key)) for key in sorted(self.fields)
if field_values.get(key) ] # keep fields in same order
# insert date to beginning
data.insert(0, strftime("%Y-%m-%d %H:%M:%S", localtime()))
writer.writerow(data)
# now file is automatically closed

When you open a file the data should be written to that. If you want to
move existing data from logfile.txt into user opened file then you need
to read logfile.txt and then write it to the user opened file. To make
your life simpler, either pass in the file path or open the file save
dialog on __init__.
