How Can I write a PL/SQL routine that will generate a "CREATE TABLE" that will populate the table name from a value in existing table?

---The only columns and datatypes are to be hardcoded that will be inserted into each new table structure are below:
This is example of a SQL statement to hard code the columns NAME AND DESCRITION.
 
PLEASE NOTE: OBJ_TYPE_NAMES ARE IN THE obj_type TABLE ONLY****
SQLstatement = "create table" + obj_type_nm 	
SQLstatement = SQLstatement " "\n" + "("
SQLstatement = SQLstatement " "\n" + "name		varchar2(100)	not null,"
SQLstatement = SQLstatement " "\n" + "description	varchar2(400)	null"
 
The CODE should work like this:
 
Loop through each existing table and first find the NEW TABLE NAME from the OBJ_TYPE Table which would be 
<DESIGN_SPECIFICATION> Based on THE FIRST ID NUMBER "OBJ_TYPE_ID" = 1
 
Then the code should find the NEXT TABLE "OBJ_TYPE_RLTNSHP" and extract the COLUMN value from the column named
OBJ_TYPE_NM based on the OBJ_TYPE_ID  = 1 WHICH WOULD BE in this case <DATA TYPE>
 
Then the code should go to the last table based on the same parameters in the next table "PRPRT" and 
extract the column value from the column name "prt_nm" where OBJ_TYPE_ID =1 which would be in this case <ERP_NO>
and so forth, this is just and EXAMPLE 
 
***PLEASE FEEL FREE TO CHANGE THE SQL statements, I was just trying to figure out a way to hard code the name and description columns since they should generate in every table.
 
 
 
These are the EXISTING TABLES which we will be extracting the NEW table NAME and columns, datatypes and attributes.
 
Table Name: Obj_Type
 
Coulumn1	Column2
Obj_type_ID	Obj_type_nm
1		Design_Specification
2		Attribute
3		Entity
 
 
Table Name:OBJ_TYPE_RLTNSHP
Column1		Column2		Column3
OBJ_TYPE_ID	Data Type	Obj_type_mndtry_in
1		FK		String
2		PK		String
3		REQUIRED	Number
 
Table Name: Prprt
Column1:	Column2		Column3
prt_id		prt_nm		prt_size
1		erp_no		100
2		release		200
3		version		50
 
--Results of the Create Table STATEMENTS would return a table structure similar below:
 
Create Table Data_Specification
 
Name		Varchar(200)		not null,
Description	varchar2(400)		null,
Data Type	String(20)		not null,
FK		String(1)		not null,
PK		String(1)		not null,
Required	string(1)		not null
);
 
Create Table Attribute
Description	varchar2(400)		null,
Data Type	String(20)		not null,
ERP_NO		String(100)		not null,
Release		String(200)		not null,
Version		String(50)		not null,
);
