menu driven interface

I need help doing a menu driven database program. I need a Main Menu, with a few options. One of the options is to create a new record in a table. Can anyone help me go from a main menu screen to the actual database to create a new entry?
Thanx! :D

Code:

---

do{
      printf("1.  Make a new database\n");
      printf("2.  Add a person\n");
      printf("3.  Remove a person\n");
      /*blah blah blah*/
      fgets(buffer,sizeof buffer,stdin);
  while(buffer[0]!=1|| buffer[0]!=2|| buffer[0]!=3);
  if(buffer[0]==1)
      add_database();
  /*blah blah rest of code*/

---

> buffer[0]!=1
Should be
buffer[0]!='1'

you knew what I meant :D

Thanx :D
