function build_Form() 
     
    local gui = {} 
    gui._placeHolders = {} 
    local dicht = guiSetVisible ( build_Form, false ) 
      
    local screenWidth, screenHeight = guiGetScreenSize() 
    local windowWidth, windowHeight = 842, 498 
    local left = screenWidth/2 - windowWidth/2 
    local top = screenHeight/2 - windowHeight/2 
    showCursor(true) 
     
    gui["_root"] = guiCreateWindow(left, top, windowWidth, windowHeight, "Form", false) 
    guiWindowSetSizable(gui["_root"], false) 
     
    gui["tabWidget"] = guiCreateTabPanel(0, 75, 821, 431, false, gui["_root"]) 
     
    gui["tab"] = guiCreateTab("United States Department of Homeland Security ", gui["tabWidget"]) 
     
    gui["plainTextEdit"] = guiCreateMemo(10, 10, 401, 361, "The Department of homeland security was founded in this server by tim260.\n\nIts now lead by tim260 and is not active yet we are devloping it.", false, gui["tab"]) 
    guiMemoSetReadOnly(gui["plainTextEdit"], true) 
  
     
    gui["label_2"] = guiCreateLabel(460, 90, 271, 221, "", false, gui["tab"]) 
    guiLabelSetHorizontalAlign(gui["label_2"], "left", false) 
    guiLabelSetVerticalAlign(gui["label_2"], "center") 
     
    gui["tab_3"] = guiCreateTab("Joining", gui["tabWidget"]) 
     
    gui._placeHolders["line"] = {left = 27, top = 180, width = 751, height = 20, parent = gui["tab_3"]} 
     
    gui["tab_2"] = guiCreateTab("Members", gui["tabWidget"]) 
     
    gui["label"] = guiCreateLabel(290, 25, 411, 31, "Homeland security info panel", false, gui["_root"]) 
    guiLabelSetHorizontalAlign(gui["label"], "left", false) 
    guiLabelSetVerticalAlign(gui["label"], "center") 
     
    return gui, windowWidth, windowHeight 
end
