See the other posts re the wisdom of using Python 3 at this stage, 
however....

>>> from tkinter import *
>>> tk = Tk()
>>> c = Canvas(tk, height=100,width=100)
>>> c.pack()
>>> c.create_line(0,15,30,75)
1
>>> c.create_oval(50,70,80,90)
2
>>> tk.mainloop()

2)how to plot a pixel. Basically that's all  a "graphics package" needs. 

There is no pixel method per say but you can plot a single pixel 
sized oval.

c.create_oval(4,4,4,4)

Which is hard to see but here is a fuller example:

>>> tk = Tk()
>>> c = Canvas(tk, height=100,width=100)
>>> c.pack()
>>> for x in range(25,50):
            c.create_oval(x,x,x,x)

>>> tk.mainloop()

3) Is this the right group?
Yes.
