Yes you can.

Uhm.. I'm sure it is more a question of learning how to use them properly.
The following code should be very close to the original request,
depending on the tk version some minor modifications may be needed.

from Tkinter import Tk, Button, Checkbutton, Label, Entry, Frame

class App:
    def __init__(self, master):
        column0_padx = 24
        row_pady = 36

        #Label 1
        lbl_testcase_exec = Label(master, text="Test case execution",
                                  wraplength=100, anchor='w', justify='left')
        lbl_results_cmp = Label(master, text="Results comparison",
                                wraplength=100, justify='left')
        lbl_tolerance = Label(master, text="Tolerance (5%)", wraplength=100)
        testcase_exec = Checkbutton(master)
        results_cmp = Checkbutton(master)
        tolerance = Entry(master, width=4)
        lbl_analysis = Label(master, text="Analysis Library")
        analysis_lib = Entry(master, width=30)

        lbl_testcase_exec.grid(row=0, column=2, padx=20, pady=12, sticky='w')
        lbl_results_cmp.grid(row=0, column=3, pady=12, sticky='w')
        lbl_tolerance.grid(row=0, column=4, padx=20, pady=12, sticky='wn')
        lbl_analysis.grid(row=1, column=0, sticky='w', padx=column0_padx)
        analysis_lib.grid(row=1, column=1, sticky='w')
        testcase_exec.grid(row=1, column=2, padx=20, sticky='w')
        results_cmp.grid(row=1, column=3, sticky='w')
        tolerance.grid(row=1, column=4, padx=20, sticky='w')

        #Label 2
        lbl_ref_analysis = Label(
            master, text="Reference Analysis Libary Version",
            wraplength=150, justify='left', pady=row_pady)
        ref_analysis_lib = Entry(master, width=30)
        lbl_ref_analysis.grid(row=2, column=0, sticky='w', padx=column0_padx)
        ref_analysis_lib.grid(row=2, column=1, sticky='w')

        # version
        lbl_version = Label(master, text="Version under Test")
        version = Label(master, text="vA.B.C.D")
        lbl_version.grid(row=3, column=0, sticky='w', padx=column0_padx)
        version.grid(row=3, column=1, sticky='w')

        # test all
        lbl_testall = Label(master, text="Test All")
        testall = Checkbutton(master)
        lbl_testall.grid(row=4, column=0, pady=row_pady, padx=column0_padx,
                         sticky='w')
        testall.grid(row=4, column=1, sticky='w')

        # buttons
        bottom_frame = Frame(master)
        bottom_frame.grid(row=5, column=1, columnspan=3, sticky='w')

        btn_start = Button(bottom_frame, text = "Go", width=7)
        btn_start.pack(side='left')
        btn_commit = Button(bottom_frame, text="Commit", width=7)
        btn_commit.pack(side='left', padx=80)
        btn_exit = Button(bottom_frame, text="Exit", width=7)
        btn_exit.pack(side='left')


root = Tk()
root.title("Test Automation")
root.minsize(800, 400)
app = App(root)
root.mainloop()
