need help with GUI

[the godfather01]

i got some questions about swing and i need help in it:

when am working with netbeans can i set the x location and y location of a JArea?.

Q2: can i divide a textarea or textboxto have cells (to be like a ghant chart)?

Q3: can i add swing objects at run time?

[SwinGirl]

setLocation (x,y);
----
setColumns(int c);
setRows(int r);

----

excuseme, i´m in a doubt with that.(adding swing objs at runtime)
SwiXml seems to be useful.
I didn´t needed to do that, anyway.
