Untested code, but somehow like this it should work (maybe 
"ControlCount" and "Controls" are named differently...):

=== code begin ===

c := 0;
for i := 0 to frmMain.ControlCount - 1 do
   if (frmMain.Controls[i] is TButton) and (Pos('btnMacro', 
frmMain.Controls[i].Name) = 1) then begin
     frmMain.Controls[i].Caption := MacroList[c].Name;
     Inc(c);
   end;

=== code end ===
