Hi,
Some comments on your code:

Here's a *BUG* - you are trying to use *strcat* on non-initialized char* 
pointer. Use *g_strdup()* instead of *strcat()* to duplicate the string 
from widget.

Get a pointer to widget "dateedit1" first, and use *GNOME_DATE_EDIT()* 
cast instead of (GnomeDateEdit*) to be sure that the right widget was 
loaded.

1. Use *g_malloc()*  or even *g_malloc0()* function instead of 
*malloc()* - its easier to debug your app if memory allocation fails.
2. Use GList or GSList data type from GLib - these are already 
implemented double and single linked lists. Why are you trying to 
reimplement the wheel ?
