import socket
import sys
import os
import kivy
from kivy.app import App
from kivy.uix.button import Button
from kivy.uix.image import Image
from kivy.uix.textinput import TextInput
from kivy.uix.boxlayout import BoxLayout

    def build(self):

        layout = BoxLayout(padding=10, orientation='vertical')
        btn1 = Button(text="OK", size_hint=(0.49, 0.1),pos_hint={'x': .51, 'center_y': .5})
        btn1.bind(on_press=self.buttonClicked)
        layout.add_widget(btn1)
        self.txt1 = TextInput(multiline=False, text='',
                                           size_hint=(0.5, 0.1))
        layout.add_widget(self.txt1)
        self.lbl1 = Label(text="Write your guess in the blank text box", size_hint=(1, None), height=30)
        layout.add_widget(self.lbl1)

        return layout

    def buttonClicked(self,btn):
        print "hi"

TextInputApp().run()

You could create another BoxLayout with horizontal orientation to harbor the Button and TextInput.

class TextInputApp(App):
    def build(self):

        layout = BoxLayout(padding=10, orientation='vertical')
        # Second boxlayout
        layout2 = BoxLayout()
        # Add BoxLayout do main layout
        layout.add_widget(layout2)

        # Drop old size and pos_hints
        btn1 = Button(text="OK")
        btn1.bind(on_press=self.buttonClicked)
        # Add Button to secondary boxlayout
        layout2.add_widget(btn1)
        self.txt1 = TextInput(multiline=False, text='',
                                           size_hint=(0.5, 0.1))
        layout.add_widget(self.txt1)
        # Drop size_hint
        self.lbl1 = Label(text="Write your guess in the blank text box")
        layout2.add_widget(self.lbl1)

        return layout

If you want to change the size of the Button and TextInput, you can set that in the secondary BoxLayout:

layout2 = BoxLayout(size_hint_y=None, height=30)
