Maybe try with easygui [1]. The multenterbox [2] seem to be right to 
enter 4 values [3]... Its really a nice tool to have a quick and clean 
user input solution with GUI in a function.

A+

MULTENTERBOX AND MULTPASSWORDBOX --
	GETTING INFORMATION FROM THE USER ABOUT MULTIPLE FIELDS
=======================================================================

Multenterbox is a simple way of showing multiple enterboxes on a single
screen.  Multpasswordbox has the same interface as multenterbox, but
when it is displayed, the last of the fields is assumed to be a
password, and is masked with asterisks.

def multenterbox(message="Fill in values for the fields."
     , title=""
     , argListOfFieldNames  = []
     , argListOfFieldValues = []
     ):
     """Show screen with multiple data entry fields.
     The third argument is a list of fieldnames.
     The the forth argument is a list of field values.

     If there are fewer values than names, the list of values is padded
     with empty strings until the number of values is the same as the
     number of names.

     If there are more values than names, the list of values
     is truncated so that there are as many values as names.

     Returns a list of the values of the fields,
     or None if the user cancels the operation.

     Here is some example code, that shows how values returned from
     multenterbox can be checked for validity before they are accepted.
     --------------------------------------------------------------
     msg = "Enter your personal information"
     title = "Credit Card Application"
     fieldNames = ["Name","Street Address","City","State","ZipCode"]
     fieldValues = []  # we start with blanks for the values
     fieldValues = multenterbox(msg,title, fieldNames)

     # make sure that none of the fields was left blank
     while 1:
         if fieldValues == None: break
         errmsg = ""
         for i in range(len(fieldNames)):
            if fieldValues[i].strip() == "":
                errmsg = errmsg + ('"%s" is a required field.\n\n' %
                            fieldNames[i])
         if errmsg == "": break # no problems found
         fieldValues = multenterbox(errmsg, title, fieldNames,
                             fieldValues)

     print "Reply was:", fieldValues
