Here's a demo of what I mentioned earlier. Notice how I create a child Window, Icon, and EditText. Then I made a quick routine to apply the correct styling and another to handle the resize event.

 
include Win32Lib.ew 
without warning 
 
integer r_Box_onResize 
 
procedure makeEditBox( integer box, integer image, integer edit, object icon ) 
    setUserProperty( box, "Image", image ) 
    setUserProperty( box, "Edit",  edit  ) 
    addStyle( box, {WS_BORDER,WS_EX_CLIENTEDGE} ) 
    removeStyle( edit, {WS_BORDER,WS_EX_CLIENTEDGE} ) 
    setWindowBackColor( image, getSysColor(COLOR_WINDOW) ) 
    setIcon( image, icon ) 
    setHandler( box, w32HResize, r_Box_onResize ) 
end procedure 
 
procedure Box_onResize( integer pSelf, integer pEvent, sequence pParams ) 
 
    object image, edit 
    sequence rect 
     
    image = getUserProperty( pSelf, "Image" ) 
    edit  = getUserProperty( pSelf, "Edit"  ) 
     
    rect = getClientRect( pSelf ) 
    setRect( image[1], 0, 0, 16, rect[4], w32True ) 
    setRect( edit[1], 16, 0, rect[3]-16, rect[4], w32True ) 
 
end procedure 
r_Box_onResize = routine_id("Box_onResize") 
 
constant  
    Main        = create( Window, "EditText w/image", 0, Default, Default, 480, 70, 0 ), 
    Box         = create( Window, "", Main, 0, 0, 0, 0, {WS_CHILD+WS_VISIBLE} ), -- mind your styles here 
    Image       = create( Icon, "", Box, 0, 0, 0, 0, 0 ), 
    Edit        = create( EditText, "", Box, 0, 0, 0, 0, 0 ), 
    Btn         = create( Button, "Click", Main, 0, 0, 0, 0, 0 ) 
     
    makeEditBox( Box, Image, Edit, extractIcon({"pilcrow.ico", 1}) ) 
 
procedure Main_onResize( integer pSelf, integer pEvent, sequence pParams ) 
 
    setRect( Box, 10, 9, {w32Edge,-100}, 22, w32True ) 
    setRect( Btn, {w32AltEdge,-90}, 8, 80, 24, w32True ) 
 
end procedure 
setHandler( Main, w32HResize, routine_id("Main_onResize") ) 
 
procedure Btn_onClick( integer pSelf, integer pEvent, sequence pParams ) 
 
    VOID = message_box( '"' & getText(Edit) & '"', "Text", MB_ICONINFORMATION ) 
 
end procedure 
setHandler( Btn, w32HClick, routine_id("Btn_onClick") ) 
 
WinMain( Main, Normal ) 

Here's the icon I used in the demo: pilcrow.ico
