PowerShell
The following will only work in the PowerShell console host. Most notably it will not work in the PowerShell ISE.
$Host.UI.RawUI.CursorPosition = New-Object System.Management.Automation.Host.Coordinates 2,5

Alternatively, in any PowerShell host that uses the Windows console, one can directly use the .NET Console
class:
[Console]::SetCursorPosition(2,5)
[Console]::Write('Hello')

Python
Using ANSI escape sequence, where ESC[y;xH moves curser to row y, col x:
print("\033[6;3HHello")
On Windows it needs to import and init the [http://code.google.com/p/colorama/ colorama] module first.
ANSI sequences are not recognized in Windows console, here is a program using Windows API:
from ctypes import *
STD_OUTPUT_HANDLE = -11
class COORD(Structure):
pass
COORD._fields_ = [("X", c_short), ("Y", c_short)]
def print_at(r, c, s):
h = windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)
windll.kernel32.SetConsoleCursorPosition(h, COORD(c, r))
c = s.encode("windows-1252")
windll.kernel32.WriteConsoleA(h, c_char_p(c), len(c), None, None)
print_at(6, 3, "Hello")

The REXX language doesn't have any cursor or screen management tools, but some REXX interpreters have added the functionality via different methods. {{works with|PC/REXX, Personal REXX}}
/*REXX program demonstrates cursor position and writing of text to same.*/

say 'Hello' /*write the text at that location*/
call scrwrite 30,50,'Hello.' /*another method. */
call scrwrite 40,60,'Hello.',,,14 /*another ... in yellow.*/
