Python tkinter example

from Tkinter import *  # Python 2
# from tkinter import *  # Python 3

class GuiRec(Frame):  # We're going to "inherit" the Frame class. 
    def __init__(self, master, rec):  # What happens when you initialize the GuiRec
        Frame.__init__(self, master)  # Like any frame, you gotta set the parent.

        self.record = rec

        # You could also make these "public properties" or whatever. Your call.
        self.fields = rec.keys()
        self.fields.sort()  # for now, let's sort these alphabetically

        self.labels = []
        self.entries = []

        # We need to add a row for each key/value pair.
        # That means 1 Label and one Entry
        for i in range(len(self.fields)):
            name = self.fields[i]

            lbl = Label(self, text=name)
